Augustine of Hippo : If they are not seen, how can you be convinced that they exist? Well, where do these things that you see come from, if not from one whom you cannot see? Yes, of course you see something in order to believe something, and from what you can see to believe what you cannot see. Please do not be ungrateful to the one who made you able to see; this is why you are able to believe what you are not yet able to see. God gave you eyes in your head, reason in your heart. Arouse the reason in your heart, get the inner inhabitant behind your inner eyes on his feet, let him take to his windows, let him inspect God's creation. — SERMON 126.3 Augustine of Hippo : When you hope, you do not yet have what you are hoping for, but, by believing it, you resemble someone who does possess it. For faith will eventually take hold, but our very faith stands for the thing itself. I mean, you do not have your hands on anything when you have them on faith, nor are they empty if they are full of faith. The reason faith is greatly rewarded is that it does not see and yet believes. I mean, if it could see, what reward would there be?... But faith does not falter, because it is supported by hope. Take away hope, and faith falters. How, after all, when you are walking somewhere, will you even move your feet, if you have no hope of ever getting there? If, though, from each of them, that is from faith and hope, you withdraw love, what is the point of believing; what is the point of hoping, if you do not love? Indeed, you cannot even hope for anything you do not love. Love, you see, kindles hope; hope shines through love. But when we attain the things that we have been hoping for while believing in and not seeing them, what faith will there be then to be praised? Considering that "faith is the conviction of things not seen," when we do see, it will not be called faith. After all, you will be seeing, not believing. — SERMON 359A.3-4 Clement of Alexandria : But faith, which the Greeks disparage, deeming it futile and barbarous, is a voluntary preconception, the assent of piety-"the subject of things hoped for, the evidence of things not seen," according to the divine apostle. "For hereby," pre-eminently, "the elders obtained a good report. But without faith it is impossible to please God." Others have defined faith to be a uniting assent to an unseen object, as certainly the proof of an unknown thing is an evident assent. If then it be choice, being desirous of something, the desire is in this instance intellectual. And since choice is the beginning of action, faith is discovered to be the beginning of action, being the foundation of rational choice in the case of any one who exhibits to himself the previous demonstration through faith. Voluntarily to follow what is useful, is the first principle of understanding. Unswerving choice, then, gives considerable momentum in the direction of knowledge. The exercise of faith directly becomes knowledge, reposing on a sure foundation. — The Stromata Book 2 Clement of Alexandria : "Let not the waters of thy fountain overflow, and let thy waters spread over thine own streets." For it is not many who understand such things as they fall in with; or know them even after learning them, though they think they do, according to the worthy Heraclitus. Does not even he seem to thee to censure those who believe not? "Now my just one shall live by faith," the prophet said. And another prophet also says, "Except ye believe, neither shall ye understand." For how ever could the soul admit the transcendental contemplation of such themes, while unbelief respecting what was to be learned struggled within? But faith, which the Greeks disparage, deeming it futile and barbarous, is a voluntary preconception, the assent of piety-"the subject of things hoped for, the evidence of things not seen," according to the divine apostle. "For hereby," pre-eminently, "the elders obtained a good report. But without faith it is impossible to please God." — The Stromata Book 2 Cyril of Jerusalem : "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. — Catechetical Lecture 5:1-2 Cyril of Jerusalem : 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. — Catechetical Lecture 5:3 Ephrem the Syrian : Now our faith is not destroyed by despair because it was made firm by true hope. — COMMENTARY ON THE EPISTLE TO THE HEBREWS Gregory the Dialogist : But he touched, and exclaimed: My Lord, and my God. Jesus says to him: Because you have seen me, Thomas, you have believed. Since the apostle Paul says: Now faith is the substance of things hoped for, the evidence of things not appearing, it is certainly clear that faith is the evidence of those things which cannot appear. For those things which appear no longer have faith, but recognition. Therefore when Thomas saw, when he touched, why is it said to him: Because you have seen me, you have believed? But he saw one thing, he believed another. For divinity could not be seen by a mortal man. Therefore he saw the man, and confessed God, saying: My Lord, and my God. Therefore by seeing he believed, who considering the true man, exclaimed that this was God, whom he could not see. — Forty Gospel Homilies, Homily 26 Gregory the Dialogist : But if, according to the words of Paul, faith is the substance of things hoped for, the evidence of things not seen, we can no longer tell you to believe in the life to come, because behold, those who live in that life are visibly presented to human eyes. For what can be seen is better said to be known than believed. Therefore the Lord wished us to know the life to come rather than merely believe in it, since he visibly shows us that those whom he invisibly receives live with him. — Forty Gospel Homilies, Homily 32 John Chrysostom : "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." — Homily on Hebrews 21 Leo the Great : 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. — SERMON 69.2 Oecumenius : 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. — The Pseudo-Oecumenian Catena on Hebrews Tertullian : You must know that in the eye of perfect, that is, Christian, modesty, (carnal) desire of one's self (on the part of others) is not only not to be desired, but even execrated, by you: first, because the study of making personal grace (which we know to be naturally the inviter of lust) a mean of pleasing does not spring from a sound conscience: why therefore excite toward yourself that evil (passion)? why invite (that) to which you profess yourself a stranger? secondly, because we ought not to open a way to temptations, which, by their instancy, sometimes achieve (a wickedness) which God expels from them who are His; (or, ) at all events, put the spirit into a thorough tumult by (presenting) a stumbling-block (to it). We ought indeed to walk so holily, and with so entire substantiality of faith, as to be confident and secure in regard of our own conscience, desiring that that (gift) may abide in us to the end, yet not presuming (that it will). — On the Apparel of Women Book II Theodore of Mopsuestia : 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." — FRAGMENTS ON THE EPISTLE TO THE Hebrews 11.1-2 Theodoret of Cyrus : 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. — INTERPRETATION OF Hebrews 11
