Hebrews 11:2

“Should your springs be scattered abroad, streams of water in the streets?” “The majority do not turn their minds to the sort of things they encounter, and, if they are taught, they do not acquire knowledge, although they think they do.” So says the admirable Heraclitus. Do you not realize that he is another critic of nonbelievers? “The righteous shall live by his faith,” says the prophet. One of the other prophets remarks, “If you do not believe, you emphatically will not understand either.” How could a soul come to the study of these things, itself exceptional, if, deep within, lack of faith over the teaching is fighting against it? Faith, which the Greeks think alien and useless and which they consequently malign, is in fact preconception by the will, an act of consenting to religion and, as the divine apostle puts it, “the assurance of things hoped for, the conviction of things not seen. For by it the men of old received divine approval.” Without faith it is impossible to please God.

Now our faith is not destroyed by despair because it was made firm by true hope. And there are witnesses who testify about it. In fact, even though faith was hidden from the people of the middle generation, it had nonetheless been revealed to those of the first. And there is a proof that reveals what is not evident. What proof? Certainly the one through which the testimony about the people of the first generation was made, that is, the narrative of scripture, that testified about the faith, through which the ancient fathers were put to test.

It is not only among those of us who bear the name of Christ that the dignity of faith is great. Rather, all things that are accomplished in the world, even by those who are strangers to the church, are accomplished by faith. By faith the laws of marriage yoke together those who have lived as strangers. Because of the faith in marriage contracts, a stranger is made partner of another stranger’s person and possessions. By faith, farmers are also sustained, for the one who does not believe that he shall receive a harvest is not going to endure the work. By faith seafaring men, trusting to the thinnest plank, exchange that most solid element, the land, for the restless motion of the waves, committing themselves to uncertain hopes and carrying with them a faith more sure than any anchor. By faith therefore most of men’s affairs are held together: and not among us only has there been this belief, but also, as I have said, among those who are outside the church. For if they receive not the Scriptures but bring forward certain doctrines of their own, even these they accept by faith.

“Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report.” Notice how great a dignity the Lord bestows on you in transferring you from the order of catechumens to that of the faithful. The apostle Paul says as much when he affirms, “God is faithful, by whom you were called into the fellowship of his son Jesus Christ.” Since God is here called faithful, you also in receiving this title receive a great dignity. God is called faithful in the same way that he is called good, just, almighty and maker of the universe. Consider therefore to what kind of dignity you are rising, seeing you are to become a partaker of a title of God.Here, then, it is further required that each of you be found faithful in his conscience: “for a faithful man it is hard to find”—not that you need to reveal to me what is on your conscience, for you are not to be “judged by man’s judgment.” But you are supposed to show the sincerity of your faith to God, “who tries the reins and hearts” and “knows the thoughts of men.” A faithful person is a great thing, being richest of all rich people. For “to the faithful person belongs the whole world of wealth,” in that he disdains and tramples on it. For they who in appearance are rich and have many possessions are poor in soul: since the more they gather, the more they pine with longing for what is still lacking. But the faithful person (a strange paradox, indeed) is rich in poverty. Such a person knows that we only need to have “food and clothing” and, being “content with these,” he has trampled riches under foot.

"Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report." O what an expression has he used, in saying, "an evidence of things not seen." For we say there is "evidence," in the case of things that are very plain. Faith then is the seeing things not plain (he means), and brings what are not seen to the same full assurance with what are seen. So then neither is it possible to disbelieve in things which are seen, nor, on the other hand can there be faith unless a man be more fully assured with respect to things invisible, than he is with respect to things that are most clearly seen. For since the objects of hope seem to be unsubstantial, Faith gives them substantiality, or rather, does not give it, but is itself their substance. For instance, the Resurrection has not come, nor does it exist substantially, but hope makes it substantial in our soul. This is the meaning of "the substance of things."

If therefore it is an "evidence of things not seen," why forsooth do you wish to see them, so as to fall away from faith, and from being just? Since "the just shall live by faith," whereas ye, if ye wish to see these things, are no longer faithful. Ye have labored (he says), ye have struggled: I too allow this, nevertheless, wait for this is Faith: do not seek the whole "here."

He has made use of many proofs, since he knew the Jews especially questioned faith by means of a certain line of argument. For the Jews were setting forth the law and righteousness by their works, but Christians set forth faith, saying that even if someone should be guilty of ten thousand evils, by only believing in Christ he receives immediately deliverance from all of them, being deemed worthy of justification from him. Therefore, having determined this, then partly to appropriate the things that had been said before and partly to be able to show that faith appeared among all the virtuous men of old, he adds, “by faith the men of old received divine approval.”

The body’s eye did not recognize the God of all as creator; instead faith instructed us that God, who has always existed, created what did not exist. There is, after all, no example of this among human beings; yet though learning nothing of the kind from nature, we have in faith a teacher of the unexpected. Human beings, of course, make something out of something, whereas the God of all produced what exists out of nothing.

He shows both those before the law and those under the law becoming God’s friends through faith and enjoying distinction. In this he achieves two things at the same time: he brings out the power of faith (faith accomplishing what the law did not achieve) and provides encouragement to those dispirited at the insurrections of the adversaries, showing everyone in possession of everlasting repute to have traveled through the same storms. First he teaches the very definition of faith: through it we see what is unseen, and it acts as an eye for discernment of what is hoped for. Faith depicts for us in advance the resurrection of those still lying dead in their tombs and causes the immortality of the dust of our bodies to become evident.

Rejoice that whatever the shadows of the Old Testament used to veil beneath the testimonies of prophets has been brought out into the open through the mystery of the Lord’s passion. As a result, the various kinds of sacrifices and the different means of purification have come to a halt. Thus, the precept of circumcision, the distinction between foods, the sabbath rest, and the killing of the paschal lamb have ceased, since “the law was given through Moses, but grace and truth came through Jesus Christ.”Figures came first so that their fulfillment could follow. When the reality which had been announced finally arrived, there was no longer any need for the services of heralds. Reconciliation of the human race was conducted in such a way that the salvation which comes in Christ should have been available to all generations under the same justification. Delaying this salvation was a calculated move. It had the advantage of causing those things which were believed long before they actually took place to be honored without interruption. When the strength of faith has been established in those things that do not lie open to our vision, heavenly doctrine treats us more leniently.… To help us understand more easily, we benefit from many more prophets and witnesses than former ages.

It consequently expresses what faith is, and says: Faith is the substance and essence of those thingswhich arehoped for. For since those things that exist in hope cannot be perceived, as they are not present in the meantime, faith is a certain essence and substance of them, causing them to be and in a way to become present, because one believes them to be. Moreover, faith is the proof and demonstration of things that are not seen. For faith presents visible things that are invisible. How? By the mind itself seeing those things that do not appear.

“for by it the elders have obtained a good report.” By faith, they received a report from God that they were pleasing to Him.

"the elders." Who are they? About whom Paul is about to speak.

"Through faith we understand that the ages were formed." For what reason could this be demonstrated? Therefore, it is necessary to persuade oneself by faith:

"so that what is seen was not brought into being from anything visible." For what word will demonstrate that those things were brought into being from what was not visible?None; but faith alone. Therefore, by faith we understand the ages to have been framed, that is, to have come into being, by the word of God. Why, by faith? So that the visible things did not come from things appearing; because the visible things came from things not appearing; the man of faith is needed.

"Abel offered to God a more excellent sacrifice." For whose example did Abel honor God, except that he believed by faith that there would be a compensation for these things?

"by which he obtained a report that he was righteous." For when God said to Cain, "If you offer rightly, but do not divide rightly," (Gen. 4:7) He testified concerning Abel that he both offered rightly and divided rightly. It is also said that fire descended from heaven upon his burnt offering.

"and by it he being dead." Indeed, the victim was the occasion for the slaughter itself.

[PHOTIUS] "yet speaks." He is immortal; his deed, done through faith, does not allow him to fall into oblivion, he says. [end of the Photius excerpt]

[OECUMENIUS] Or through itself the faith; however, it speaks through reputation, glory, by remembrance. [end of the Oecumenius excerpt]

[PHOTIUS] What is said: "and by it he being dead yet speaks," or it is understood that this victim was the occasion for envy and rivalry against his brother: moreover, this gave rise to murder. Or that he speaks through him, although dead: For this reason, it has become the cause for Abel to be remembered and regarded as unfailing. Or, if someone examines both more closely, taking into account that, through it, as it is referred to both being Dead yet Speaks: so that the meaning is: By itself or because of itself the dead host still speaks through it.
