1 John 2:6

When, however, he turns their minds back to continence, ("But I will you all so to be,") "I think, moreover," he says, "I too have the Spirit of God; "in order that, if he had granted any indulgence out of necessity, that, by the Holy Spirit's authority, he might recall. But John, too, when advising us that "we ought so to walk as the Lord withal did," of course admonished us to walk as well in accordance with sanctity of the flesh (as in accordance with His example in other respects).

But there are some rich women, and wealthy in the fertility of means, who prefer their own wealth, and contend that they ought to use these blessings. Let them know first of all that she is rich who is rich in God; that she is wealthy who is wealthy in Christ; that those are blessings which are spiritual, divine, heavenly, which lead us to God, which abide with us in perpetual possession with God. But whatever things are earthly, and have been received in this world, and will remain here with the world, ought so to be contemned even as the world itself is contemned, whose pomps and delights we have already renounced when by a blessed passage we came to God, John stimulates and exhorts us, witnessing with a spiritual and heavenly voice. "Love not the world," says he, "neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, is lust of the flesh, and the lust of the eyes, and the pride of life, which is not from the Father, but is of the lust of the world. And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever, even as God also abideth for ever." Therefore eternal and divine things are to be followed, and all things must be done after the will of God, that we may follow the divine footsteps and teachings of our Lord, who warned us, and said, "I came down from heaven, not to do my own will, but the will of Him that sent me." But if the servant is not greater than his lord, and he that is freed owes obedience to his deliverer, we who desire to be Christians ought to imitate what Christ said and did. It is written, and it is read and heard, and is celebrated for our example by the Church's mouth, "He that saith he abideth in Christ. ought himself also so to walk even as He walked." Therefore we must walk with equal steps; we must strive with emulous walk. Then the following of truth answers to the faith of our name, and a reward is given to the believer, if what is believed is also done.

For you ought to know and to believe, and hold it for certain, that the day of affliction has begun to hang over our heads, and the end of the world and the time of Antichrist to draw near, so that we must all stand prepared for the battle; nor consider anything but the glory of life eternal, and the crown of the confession of the Lord; and not regard those things which are coming as being such as were those which have passed away. A severer and a fiercer fight is now threatening, for which the soldiers of Christ ought to prepare themselves with uncorrupted faith and robust courage, considering that they drink the cup of Christ's blood daily, for the reason that they themselves also may be able to shed their blood for Christ. For this is to wish to be found with Christ, to imitate that which Christ both taught and did, according to the Apostle John, who said, "He that saith he abideth in Christ, ought himself also so to walk even as He walked." Moreover, the blessed Apostle Paul exhorts and teaches, saying, "We are God's children; but if children, then heirs of God, and joint-heirs with Christ; if so be that we suffer with Him, that we may also be glorified together."

But if we also, beloved brethren, are in Christ; if we put Him on, if He is the way of our salvation, who follow Christ in the footsteps of salvation, let us walk by the example of Christ, as the Apostle John instructs us, saying, "He who saith he abideth in Christ, ought himself also to walk even as He walked." Peter also, upon whom by the Lord's condescension the Church was founded, lays it down in his epistle, and says, "Christ suffered for us, leaving you an example, that ye should follow His steps, who did no sin, neither was deceit found in His mouth; who, when He was reviled, reviled not again; when He suffered, threatened not, but gave Himself up to him that judged Him unjustly."

That charity and brotherly affection are to be religiously and stedfastly practised. In Malachi: "Hath not one God created us? Is there not one Father of us all? Why have ye certainly deserted every one his brother? " Of this same thing according to John: "Peace I leave with you, my peace I give unto you." Also in the same place: "This is my commandment, That ye love one another, even as I have loved you. Greater love than this has no man, than that one should lay down his life for his friends." Also in the same place: "Blessed are the peacemakers, for they shall be called the sons of God." Also in the same place: "Verily I say unto you, That if two of you shall agree on earth concerning everything, whatever you shall ask it shall be given you from my Father which is in heaven. For wherever two or three are gathered together in my name, I am with them." Of this same thing in the first Epistle to the Corinthians: "And I indeed, brethren, could not speak unto you as to spiritual, but as to carnal, as to babes in Christ. I have given you milk for drink, not meat: for while ye were yet little ye were not able to bear it, neither now are ye able. For ye are still carnal: for where there are in you emulation, and strife, and dissensions, are ye not carnal, and walk after man? " Likewise in the same place: "And if I should have all faith, so that I can remove mountains, but have not charity, I am nothing. And if I should distribute all my goods for food, and if I should deliver up my body to be burned, but have not charity, I avail nothing. Charity is great-souled; charity is kind; charity envieth not; charity dealeth not falsely; is not puffed up; is not irritated; thinketh not evil; rejoiceth not in injustice, but rejoiceth in the truth. It loveth all things, believeth all things, hopeth all things, beareth all things. Charity shall never fail." Of this same thing to the Galatians: "Thou shalt love thy neighbour as thyself. But if ye bite and accuse one another, see that ye be not consumed one of another." Of this same thing in the Epistle of John: "In this appear the children of God and the children of the devil. Whosoever is not righteous is not of God, and he who loveth not his brother. For he who hateth his brother is a murderer; and ye know that no murderer hath eternal life abiding in him." Also in the same place: "If any one shall say that he loves God, and hates his brother, he is a liar: for he who loveth not his brother whom he seeth, how can he love God whom he seeth not? " Of this same thing in the Acts of the Apostles: "But the multitude of them that had believed acted with one soul and mind: nor was there among them any distinction, neither did they esteem as their own anything of the possessions that they had; but all things were common to them." Of this same thing in the Gospel according to Matthew: If thou wouldest offer thy gift at the altar, and there rememberest that thy brother hath ought against thee; leave thou thy gift before the altar, and go; first be reconciled to thy brother, and then come and offer thy gift at the altar." Also in the Epistle of John: "God is love l and he that dwelleth in love dwelleth in God, and God in him." Also in the same place: "He who saith he is in the light, and hateth his brother, is a liar, and walketh in darkness even until now."

"He that saith he abideth in Him, ought himself also so to walk, even as He walked." How, brethren, what doth he advise us? "He that saith he abideth in Him," that is, in Christ, "ought himself also so to walk even as He walked." Haply the advice is this, that we should walk on the sea? That be far from us! It is this then, that we walk in the way of righteousness. In what way? I have already mentioned it. He was fixed upon the cross, and yet was He walking in this very way: this way is the way of charity, "Father, forgive them, for they know not what they do." If, therefore, thou have learned to pray for thine enemy, thou walkest in the way of the Lord.

There are three ways that we dwell in God—by faith, by hope and by love. God dwells in us by patience and humility.

Our hope of eternal life is in him. He is the pattern of our patience. Otherwise we are using the likeness of a false profession if we do not follow the commands of him in whose name we glory. And these would not be burdensome to us and would free us from all dangers, if we would love only what he commands us to love.

Let us follow Christ’s footsteps with the entire effort of our minds. And so that we may deserve to come to the gate of his heavenly kingdom, let us seriously consider entering it by that course of action by which he proceeded when he was spending his life on earth.

And by this we know that we have come to know him, if we keep his commandments. Whoever says, "I know him," but does not keep his commandments is a liar, and the truth is not in him. But whoever keeps his word, in him truly the love of God is perfected. By this we know that we are in him. Whoever says he abides in him ought to walk in the same way in which he walked.
"And by this we know." When John had said above that those who believed in the Lord have fellowship with him (1 Jn. 1:6), he now presents what confirms that fellowship towards him, and he says: "And by this we know that we have come to know him." This divine man often uses similar expressions in the same way: as when he says: "He was in the world, and the world was made through him, and the world did not know him." (Jn. 1:10)
Thus, therefore, John now uses the word "to know." That we know him, that is, that we are mixed with him, from this we know if we observe his commandments. The word γινώσκειν, that is, "to know", signifies two things, especially in sacred Scripture, namely to know something: as when it is said: "I have known that the Lord will execute judgment on the poor." (Ps. 139:1) Moreover, it signifies an all-encompassing connection and confirmation towards someone, which is called knowledge: as when it is said, "The Lord knows the ways of the innocent," (Ps. 37:18) and as Paul says, "That we may know God just as we are also known by Him." (1 Cor. 13:12) Similarly, it must be said about ignorance that it is understood in two ways. For just as it seems to external writers that there is one knowledge of opposites. According to this, therefore, to know is taken in two ways in this context. Indeed, when it says, "By this we know," it is taken for knowing; but when it is said, "That we know him," this means that we are firmly joined with him. For he who has a partnership with someone is also joined and connected to him in what he shares.
Therefore, John also adds, "we keep His commandments." From this, that is also resolved: "The Lord knows who are His," (2 Tim. 2:19) and that: "He made Him who knew no sin to be sin for us:" (2 Cor. 5:21) and anything else that is discussed in Sacred Scripture regarding knowledge or ignorance. Then, on the contrary, he confirms the same, using a more abundant proof, and says: Whoever says, "I know him," or "I have fellowship with him," and does not keep his commandments is a liar. For how can it be that the same person is joined to him and yet not joined? Certainly, keeping the commandments indicates obedience, while not observing them indicates that one is by no means a friend.
Therefore, whoever knows God is also known by Him, either having become a partner with God and united with God; and in this, the love of God is evident, through which love he will have the perfection that is in God, and by this, he will judge his closeness to God. For perfect love is indeed exhibited through works. However, since it happens that someone may convey precepts rightly and precisely, while their own affections are sluggish: this is far from God. Therefore, it is said that one who abides in God should also direct the paths of their own life according to Him.
