Pseudo-Chrysostom — Commentary on Scripture

Matthew 1:20

By addressing him as son of David, he sought to recal to his memory the promise of God to David, that of his seed should Christ be born.

Also by the words, Fear not, he desired to show that he knew the heart; that by this he might have the more faith in those good things to come, which he was about to speak concerning Christ.

There were three reasons why the Angel appeared to Joseph with this message. First, that a just man might not be led into an unjust action, with just intentions. Secondly, for the honour of the mother herself, for had she been put away, she could not have been free from evil suspicion among the unbelievers. Thirdly, that Joseph, understanding the holy conception, might keep himself from her with more care than before He did not appear to Joseph before the conception, that he should not think those things that Zacharias thought, nor suffer what he suffered in falling into the sin of unbelief concerning the conception of his wife in her old age. For it was yet more incredible that a virgin should conceive, than that a woman past the age should conceive.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 1:21

He said not, Shall bear thee a Son, as to Zacharias, Behold, Elisabeth thy wife shall bear thee a son. For the woman who conceives of her husband, bears the son to her husband, because he is more of him than of herself; but she who had not conceived of man, did not bear the Son to her husband, but to herself.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 1:24-25

Took unto him, not took home to him; for he had not sent her away; he had put her away in thought only, and now took her again in thought.

As one might say, 'He told it not so long as he lived;' would this imply that he told it after his death? Impossible. So it were credible that Joseph might have known her before the birth, while he was yet ignorant of the great mystery; but after that he understood how she had been made a temple of the Only-begotten of God, how could he occupy that? The followers of Eunomius think, as they have dared to assert this, that Joseph also dared to do it, just as the insane think all men equally mad with themselves.

It may be said, that know here signifies simply, to understand; that whereas before he had not understood how great her dignity, after the birth he then knew that she had been made more honourable and worthy than the whole world, who had carried in her womb Him whom the whole world could not contain.

Matthew 2:1-2

Let us see to what serves this designation of time. In the days of Herod the king. It shows the fulfilment of Daniel's prophecy, wherein he spake that Christ should be born after seventy weeks of years. For from the time of the prophecy to the reign of Herod, the years of seventy weeks were accomplished. Or again, as long as Judæa was ruled by Jewish princes, though sinners, so long prophets were sent for its amendment; but now, whereas God's law was held under the power of an unrighteous king, and the righteousness of God enslaved by the Roman rule, Christ is born; the more desperate sickness required the better physician. When He was born ... behold wise men, that is, immediately on His birth, showing that a great God existed in a little one of man. Or, they had set out two years before the Saviour's birth, and though they travelled all that time, neither meat nor drink failed in their scrips. Or, whence the day springs, thence came the first-fruits of the faith; for faith is the light of the soul. Therefore they came from the East, but to Jerusalem. If then any should become a…

Let us see to what serves this designation of time. In the days of Herod the king. It shows the fulfilment of Daniel's prophecy, wherein he spake that Christ should be born after seventy weeks of years. For from the time of the prophecy to the reign of Herod, the years of seventy weeks were accomplished. Or again, as long as Judæa was ruled by Jewish princes, though sinners, so long prophets were sent for its amendment; but now, whereas God's law was held under the power of an unrighteous king, and the righteousness of God enslaved by the Roman rule, Christ is born; the more desperate sickness required the better physician.

When He was born ... behold wise men, that is, immediately on His birth, showing that a great God existed in a little one of man.

Or, they had set out two years before the Saviour's birth, and though they travelled all that time, neither meat nor drink failed in their scrips.

Or, whence the day springs, thence came the first-fruits of the faith; for faith is the light of the soul. Therefore they came from the East, but to Jerusalem.

If then any should become an adulterer or homicide through means of the planets, how great is the evil and wickedness of those stars, or rather of Him who made them? For as God knows things to come, and what evils are to spring from those stars; if He would not hinder it, He is not good; if He would but could not, He is weak. Again, if it be of the star that we are either good or bad, we have neither merit nor demerit, as being involuntary agents; and why should I be punished for sin which I have done not wilfully, but by necessity? The very commands of God against sin, and exhortations to righteousness, overthrow such folly. For where a man has not power to do, or where he has not power to forbear, who would command him either to do or to forbear?

Were they then ignorant that Herod reigned in Jerusalem? Or that it is a capital treason to proclaim another King while one yet lives? But while they thought on the King to come, they feared not the king that was; while as yet they had not seen Christ, they were ready to die for Him. O blessed Magi! who before the face of a most cruel king, and before having beheld Christ, were made His confessors.

Matthew 2:3-6

Were they then ignorant that Herod reigned in Jerusalem? Or that it is a capital treason to proclaim another King while one yet lives? But while they thought on the King to come, they feared not the king that was; while as yet they had not seen Christ, they were ready to die for Him. O blessed Magi! who before the face of a most cruel king, and before having beheld Christ, were made His confessors. Herod was troubled when he heard that a King was born of Jewish lineage, lest, himself being an Idumæan, the kingdom should return again to native princes, and himself be expelled, and his seed after him. Great station is ever obnoxious to great fears, as the boughs of trees planted in high ground move when never so little wind blows, so high men are troubled with little rumours; while the lowly, like trees in the valley, remain at peace. Both have their own causes of jealousy, both fear a successor in their kingdom; Herod an earthly successor, the Devil a spiritual.

Were they then ignorant that Herod reigned in Jerusalem? Or that it is a capital treason to proclaim another King while one yet lives? But while they thought on the King to come, they feared not the king that was; while as yet they had not seen Christ, they were ready to die for Him.

Herod was troubled when he heard that a King was born of Jewish lineage, lest, himself being an Idumæan, the kingdom should return again to native princes, and himself be expelled, and his seed after him. Great station is ever obnoxious to great fears, as the boughs of trees planted in high ground move when never so little wind blows, so high men are troubled with little rumours; while the lowly, like trees in the valley, remain at peace.

Both have their own causes of jealousy, both fear a successor in their kingdom; Herod an earthly successor, the Devil a spiritual. Even Jerusalem is troubled, which should have rejoiced at that news, when a Jewish King was said to be risen up. But they were troubled, for the wicked cannot rejoice at the coming of the good. Or perhaps it was in fear that Herod should wreak his wrath against a Jewish King on his race.

Why does Herod make this enquiry, seeing he believed not the Scriptures? Or if he did believe, how could he hope to be able to kill Him whom the Scriptures declared should be King? The Devil instigated him, who believed that Scripture lies not; such is the faith of devils, who are not permitted to have perfect belief, even of that which they do believe. That they do believe, it is the force of truth constrains them; that they do not believe, it is that they are blinded by the enemy. If they had perfect faith, they would live as about to depart from this world soon, not as to possess it for ever.

When they should have kept secret the mystery of the King appointed of God, especially before a foreign king, straightway they became not preachers of the word of God, but revealers of His mystery. And they not only display the mystery, but cite the passage of the prophet, viz. Micah.

By cutting short the prophecy, they became the cause of the murder of the Innocents. For the prophecy proceeds, From thee shall go forth a King who shall feed My people Israel, and His day shall be from everlasting. Had they cited the whole prophecy, Herod would not have raged so madly, considering that it could not be an earthly King whose days were spoken of as from everlasting.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 2:7-9

As soon as Herod had heard the answer, though doubly authenticated, both by the authority of the Priests, and the passage from the Prophets, he yet turned not to worship the King that was to be born, but sought how he might put Him to death by subtilty. He saw that the Magi were neither to be won by flattery, nor awed by threats, nor bribed by gifts, to consent to this murder; he sought therefore to deceive them; he privily called the wise men; that the Jews, whom he suspected, might not know of it. For he thought they would incline the rather to a King of theirown nation.

To induce them to do this, he put on the colour of devotion, beneath which he whetted the sword, hiding the malice of his heart under colour of humility. Such is the manner of the malicious, when they would hurt any one in secret, they feign meekness and affection.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 2:9

This passage shows, that when the star had brought the Magi nearly to Jerusalem, it was hidden from them, and so they were compelled to ask in Jerusalem, where Christ should be born? and thus to manifest Him to them; on two accounts, first, to put to confusion the Jews, inasmuch as the Gentiles instructed only by sight of a star sought Christ through strange lands, while the Jews who had read the Prophets from their youth did not receive Him, though born in their country. Secondly, that the Priests, when asked where Christ should be born, might answer to their now condemnation, and while they instructed Herod, they were themselves ignorant of Him. The star went before them, to show them the greatness of the King.

What wonder that a divine star should minister to the Sun of righteousness about to rise. It stood over the Child's head, as it were, saying, 'This is He;' proving by its place what it had no voice to utter.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 2:10-11

They rejoiced, because their hopes were not falsified but confirmed, and because the toil of so great travel had not been undertaken in vain.

By the mystery of this star they understood that the dignity of the King then born exceeded the measure of all worldly kings.

Mary His mother, not crowned with a diadem or laying on a golden couch; but with barely one garment, not for ornament but for covering, and that such as the wife of a carpenter when abroad might have. Had they therefore come to seek an earthly king, they would have been more confounded than rejoiced, deeming their pains thrown away. But now they looked for a heavenly King; so that though they saw nought of regal state, that star's witness sufficed them, and their eyes rejoiced to behold a despised Boy, the Spirit showing Him to their hearts in all His wonderful power, they fell down and worshipped, seeing the man, they acknowledged the God.

And though it were not then understood what these several gifts mystically signified, that is no difficulty; the same grace that instigated them to the deed, ordained the whole.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 2:12

Had the Magi sought Christ as an earthly King, they would have remained with Him when they had found Him; but they only worship, and go their way. After their return, they continued in the worship of God more stedfast than before, and taught many by their preaching. And when afterwards Thomas reached their country, they joined themselves to him, and were baptized, and did according to his preachingb.

It was impossible that they, who left Herod to go to Christ, should return to Herod. They who have by sin left Christ and passed to the devil, often return to Christ; for the innocent, who knows not what is evil, is easily deceived, but having once tasted the evil he has taken up, and remembering the good he has left, he returns in penitence to God. He who has forsaken the devil and come to Christ, hardly returns to the devil; for rejoicing in the good he has found, and remembering the evil he has escaped, with difficulty returns to that evil.

Next, that Christians when persecution makes it necessary should not be ashamed to fly. But why into Egypt? The Lord, who keepeth not His anger for ever, remembered the woes He had brought upon Egypt, and therefore sent His Son thither, and gives it this sign of great reconciliation, that with this one remedy He might heal the ten plagues of Egypt, and the nation that had been the persecutor of this first-born people, might be the guardian of His first-born Son. As formerly they had cruelly tyrannized, now they might devoutly serve; nor go to the Red Sea to be drowned, but be called to the waters of baptism to receive life.

The straitness of every persecution may be called night—the relief from it in like manner, day.

Matthew 2:16

When the infant Jesus had subdued the Magi, not by the might of His flesh, but the grace of His Spirit, Herod was exceeding wrath, that they whom he sitting on his throne had no power to move, were obedient to an Infant lying in a manger. Then by their contempt of him the Magi gave further cause of wrath. For when kings' wrath is stirred by fear for their crowns, it is a great and inextinguishable wrath. But what did he? He sent and slew all the children. As a wounded beast rends whatsoever meeteth it as if the cause of its smart, so he mocked by the Magi spent his fury on children. He said to himself in his fury, 'Surely the Magi have found the Child whom they said should be King;' for a king in fear for his crown fears all things, suspects all. Then he sent and slew all those infants, that he might secure one among so many.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 2:17-18

Or, it was heard on high, because uttered for the death of the innocent, according to that, The voice of the poor entereth into the heavens. (Ecclus. 35:21.) The 'weeping' means the cries of the children; 'lamentation,' refers to the mothers. In the infants themselves their death ends their cries, in the mothers it is continually renewed by the remembrance of their loss.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 2:19-20

See how Joseph was set for ministering to Mary; when she went into Egypt and returned, who would have fulfilled to her this so needful ministry, had she not been betrothed? For to outward view Mary nourished and Joseph defended the Child; but in truth the Child supported His mother and protected Joseph. Return into the land of Israel; for He went down into Egypt as a physician, not to abide there, but to succour it sick with error. But the reason of the return is given in the words, They are dead, &c.

And that is said to have been done by the counsel of God for their conspiring with Herod against the Lord; as it is said, Herod was troubled, and all Jerusalem with him.

Matthew 2:21-23

They might have read this in some Prophets who are not in our canon, as Nathan or Esdras. That there was some prophecy to this purport is clear from what Philip says to Nathanael. Him of whom Moses in the Law and the Prophets did write, Jesus of Nazareth. (John 1:15.) Hence the Christians were at first called Nazarenes, at Antioch their name was changed to that of 'Christians.'

Matthew 3:1-3

The Sun as he approaches the horizon, and before he is yet visible, sends out his rays and makes the eastern sky to glow with light, that Aurora going before may herald the coming day. Thus the Lord at His birth in this earth, and before He shows Himself, enlightens John by the rays of His Spirit's teaching, that he might go before and announce the Saviour that was to come. Therefore after having related the birth of Christ, before proceeding to His teaching and baptism, (wherein he received such testimony,) he first premises somewhat of the Baptist and forerunner of the Lord. In those days, &c. In the very commencement he shows himself the messenger of a merciful Prince; he comes not with threats to the offender, but with offers of mercy. It is a custom with kings to proclaim a general pardon on the birth of a son, but first they send throughout their kingdom officers to exact severe fines. But God willing at the birth of His Son to give pardon of sins, first sends His officer proclaiming, Repent ye. O exaction which leaves none poor, but makes many rich! For even when we pay our j…

Therefore after having related the birth of Christ, before proceeding to His teaching and baptism, (wherein he received such testimony,) he first premises somewhat of the Baptist and forerunner of the Lord.

In the very commencement he shows himself the messenger of a merciful Prince; he comes not with threats to the offender, but with offers of mercy. It is a custom with kings to proclaim a general pardon on the birth of a son, but first they send throughout their kingdom officers to exact severe fines. But God willing at the birth of His Son to give pardon of sins, first sends His officer proclaiming, Repent ye. O exaction which leaves none poor, but makes many rich! For even when we pay our just debt of righteousness we do God no service, but only gain our own salvation. Repentance cleanses the heart, enlightens the sense, and prepares the human soul for the reception of Christ, as he immediately adds, For the Kingdom of Hearen is at hand.

The voice is a confused sound, discovering no secret of the heart, only signifying that he who utters it desires to say somewhat; it is the word that is the speech that openeth the mystery of the heart. Voice is common to men and other animals, word peculiar to man. John then is called the voice and not the word, because God did not discover His counsels through him, but only signified that He was about to do something among men; but afterwards by His Son he fully opened the mystery of his will.

As a great King going on a progress is preceded by couriers to cleanse what is foul, repair what is broken down; so John preceded the Lord to cleanse the human heart from the filth of sin, by the besom of repentance, and to gather by an ordinance of spiritual precepts those things which had been scattered abroad.

Matthew 3:4

Having said that he is the voice of one crying in the desert, the Evangelist well adds, John had his clothing of camel's hair; thus showing what his life was; for he indeed testified of Christ, but his life testified of himself. No one is fit to be another's witness till he has first been his own.

It becomes the servants of God to use a dress not for elegant appearance, or for cherishing of the body, but for a covering of the nakedness. Thus John wears a garment not soft and delicate, but hairy, heavy, rough, rather wounding the skin than cherishing it, that even the very clothing of his body told of the virtue of his mind. It was the custom of the Jews to wear girdles of wool; so he desiring something less indulgent wore one of skin.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 3:5-6

Having described the preaching of John, he goes on to say, There went out to him, for his severe life preached yet more loudly in the desert than the voice of his crying.

Compared with the holiness of John, who is there that can think himself righteous? As a white garment if placed near snow would seem foul by the contrast; so compared with John every man would seem impure; therefore they confessed their sins. Confession of sin is the testimony of a conscience fearing God. And perfect fear takes away all shame. But there is seen the shame of confession where there is no fear of the judgment to come. But as shame itself is a heavy punishment, God therefore bids us confess our sins that we may suffer this shame as punishment; for that itself is a part of the judgment.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 3:7-10

As a skilful physician from the colour of the skin infers the sick man's disease, so John understood the evil thoughts of the Pharisees who came to him. They thought perhaps, We go, and confess our sins; he imposes no burden on us, we will be baptized, and get indulgence for sin. Fools! if ye have eaten of impurity, must ye not needs take physic? So after confession and baptism, a man needs much diligence to heal the wound of sin; therefore he says, Generation of vipers. It is the nature of the viper as soon as it has bit a man to fly to the water, which, if it cannot find, it straightway dies; so this progeny of vipers, after having committed deadly sin, ran to baptism, that, like vipers, they might escape death by means of water. Moreover it is the nature of vipers to burst the insides of their mothers, and so to be born. The Jews then are therefore called progeny of vipers, because by continual persecution of the prophets they had corrupted their mother the Synagogue. Also vipers have a beautiful and speckled outside, but are filled with poison within. So these men's countenances…

Or who hath showed you? Was it Esaias? Surely no; had he taught you, you would not put your trust in water only, but also in good works; he thus speaks, Wash you, and be clean; put your wickedness away from your souls, learn to do well. (Is. 1:16.) Was it then David? who says, Thou shall wash me, and I shall he whiter than snow; (Ps. 51:7.) surely not, for he adds immediately, The sacrifice of God is a broken spirit. If then ye had been the disciples of David, ye would have come to baptism with mournings.

What avails noble birth to him whose life is disgraceful? Or, on the other hand, what hurt is a low origin to him who has the lustre of virtue? It is fitter that the parents of such a son should rejoice over him, than he over his parents. So do not you pride yourselves on having Abraham for your father, rather blush that you inherit his blood, but not his holiness. He who has no resemblance to his father is possibly the offspring of adultery. These words then only exclude boasting on account of birth.

Stone is hard to work, but when wrought to some shape, it loses it not; so the Gentiles were hardly brought to the faith, but once brought they abide in it for ever.

The axe is that most sharp fury of the consummation of all things, that is to hew down the whole world. But if it be already laid, how hath it not yet cut down? Because these trees have reason and free power to do good, or leave undone; so that when they see the axe laid to their root, they may fear and bring forth fruit. This denunciation of wrath then, which is meant by the laying of the axe to the root, though it have no effect on the bad, yet will sever the good from the bad.

Matthew 3:11-12

Or, John was sent to baptize, that to such as came to his baptism he might announce the presence among them of the Lord in the flesh, as himself testifies in another place, That He might be manifested to Israel, therefore am I come to baptise with water. (John 1:31.) Because then he baptized on account of Christ, therefore to them who came to him for baptism he preached that Christ should come, signifying the eminence of His power in the words, He who cometh after me is mightier than I. Or, by the feet of Christ we may understand Christians, especially the Apostles, and other preachers, among whom was John Baptist; and the shoes are the infirmities with which he loads the preachers. These shoes all Christ's preachers wear; and John also wore them; but declares himself unworthy, that he might show the grace of Christ, and be greater than his deserts. But since no one can give a benefit more worthy than he himself is, nor to make another what himself is not, he adds, He shall baptize you with the Holy Ghost and with fire. John who is carnal cannot give spiritual baptism; he baptizes…

Or, John was sent to baptize, that to such as came to his baptism he might announce the presence among them of the Lord in the flesh, as himself testifies in another place, That He might be manifested to Israel, therefore am I come to baptise with water. (John 1:31.)

Because then he baptized on account of Christ, therefore to them who came to him for baptism he preached that Christ should come, signifying the eminence of His power in the words, He who cometh after me is mightier than I.

Or, by the feet of Christ we may understand Christians, especially the Apostles, and other preachers, among whom was John Baptist; and the shoes are the infirmities with which he loads the preachers. These shoes all Christ's preachers wear; and John also wore them; but declares himself unworthy, that he might show the grace of Christ, and be greater than his deserts.

But since no one can give a benefit more worthy than he himself is, nor to make another what himself is not, he adds, He shall baptize you with the Holy Ghost and with fire. John who is carnal cannot give spiritual baptism; he baptizes with water, which is matter; so that he baptizes matter with matter. Christ is Spirit, because He is God; the Holy Ghost is Spirit, the soul is spirit; so that Spirit with Spirit baptizes our spirit. The baptism of the Spirit profits as the Spirit enters and embraces the mind, and surrounds it as it were with an impregnable wall, not suffering fleshly lusts to prevail against it. It does not indeed prevail that the flesh should not lust, but holds the will that it should not consent with it. And as Christ is Judge, He baptizes in fire, i. e. temptation; mere man cannot baptize in fire. He alone is free to tempt, who is strong to reward. This baptism of tribulation burns up the flesh that it does not generate lust, for the flesh does not fear spiritual punishment, but only such as is carnal. The Lord therefore sends carnal tribulation on his servants, that the flesh fearing its own pains, may not lust after evil. See then how the Spirit drives away lust, and suffers it not to prevail, and the fire burns up its very roots.

It is plain then that the baptismg of Christ does not undo the baptism of John, but includes it in itself; he who is baptized in Christ's name hath both baptisms, that of water and that of the Spirit. For Christ is Spirit, and hath taken to Him the body that He might give both bodily and spiritual baptism. John's baptism does not include in it the baptism of Christ, because the less cannot include the greater. Thus the Apostle having found certain Ephesians baptized with John's baptism, baptized them again in the name of Christ, because they had not been baptized in the Spirit: thus Christ baptized a second time those who had been baptized by John, as John himself declared he should, I baptize you with water; but He shall baptize you with the Spirit. And yet they were not baptized twice but once; for as the baptism of Christ was more than that of John, it was a new one given, not the same repeated.

The floor, is the Church, the barn, is the kingdom of heaven, the field, is the world. The Lord sends forth His Apostles and other teachers, as reapers to reap all nations of the earth, and gather them into the floor of the Church. Here we must be threshed and winnowed, for all men are delighted in carnal things as grain delights in the husk. But whoever is faithful and has the marrow of a good heart, as soon as he has a light tribulation, neglecting carnal things runs to the Lord; but if his faith be feeble, hardly with heavy sorrow; and he who is altogether void of faith, however he may be troubled, passes not over to God. The wheat when first thrashed lies in one heap with chaff and straw, and is after winnowed to separate it; so the faithful are mixed up in one Church with the unfaithful; but persecution comes as a wind, that, tossed by Christ's fan, they whose hearts were separate before, may be also now separated in place. He shall not merely cleanse, but throughly cleanse; therefore the Church must needs be tried in many ways till this be accomplished. And first the Jews winnowed it, then the Gentiles, now the heretics, and after a time shall Antichrist throughly winnow it. For as when the blast is gentle, only the lighter chaff is carried off, but the heavier remains; so a slight wind of temptation carries off the worst characters only; but should a greater storm arise, even those who seem stedfast will depart. There is need then of heavier persecution that the Church should be cleansed.

Matthew 3:13-15

Then, that is when John preached, that He might confirm his preaching, and Himself receive his witness.

Then, that is when John preached, that He might confirm his preaching, and Himself receive his witness. But as when the morning-star has risen, the sun does not wait for that star to set, but rising as it goes forward, gradually obscures its brightness; so Christ waited not for John to finish his course, but appeared while he yet taught.

He comes to baptism, that He who has taken upon Him human nature, may be found to have fulfilled the whole mystery of that nature; not that He is Himself a sinner, but He has taken on Him a nature that is sinful. And therefore though He needed not baptism Himself, yet the carnal nature in others needed it.

That Thou shouldest baptize me there is good cause, that I may be made righteous and worthy of heaven; but that I should baptize Thee, what cause is there? Every good gift comes down from heaven upon earth, not ascends from earth to heaven.

In this he shows that Christ after this baptized John; which is expressly told in some apocryphal booksi. Suffer now that I fulfil the righteousness of baptism in deed, and not only in word; first submitting to it, and then preaching it; for so it becometh us to fulfil all righteousness. Not that by being baptized He fulfils all righteousness, but so, in the same manner, that is, as He first fulfilled the righteousness of baptism by His deeds, and after preached it, so He might all other righteousness, according to that of the Acts, All things that Jesus began both to do and to teach. (Acts 1:1.) Or thus, all righteousness, according to the ordinance of human nature; as He had before fulfilled the righteousness of birth, growth, and the like.
