Isaías 7:9
"Unless you believe, you shall not understand," showing that as righteousness is by faith, understanding comes by wisdom. Accordingly, in the case of those who eagerly demand evident truth, we must not condemn the desire but regulate it, so that beginning with faith it may proceed to the desired end through good works. — REPLY TO FAUSTUS THE MANICHAEAN 22:53
Isaías 7:9
If you are not able to understand, believe, that you may understand. Faith goes before; understanding follows after; since the prophet says, "Unless you believe, you shall not understand. — SERMON 68 (118).1
Isaías 7:9
The mysteries and secrets of the kingdom of God first seek for believing people, that they may make them understanding. For faith is understanding's step, and understanding faith's attainment. This the prophet expressly says to all who prematurely and in undue order look for understanding and neglect faith. — SERMON 76:1
Isaías 7:9
So, then, in some points that bear on the doctrine of salvation, which we are not yet able to grasp by reason—but we shall be able to sometime—let faith precede reason, and let the heart be cleansed by faith so as to receive and bear the great light of reason; this is indeed reasonable. Therefore the prophet said with reason: "If you will not believe, you will not understand"; thereby he undoubtedly made a distinction between these two things and advised us to believe first so as to be able to understand whatever we believe. It is, then, a reasonable requirement that faith precede reason, for, if this requirement is not reasonable, then it is contrary to reason, which God forbid. But, if it is reasonable that faith precede a certain great reason that cannot yet be grasped, there is no doubt that, however slight the reason which proves this, it does precede faith. — LETTER 120
Isaías 7:14
Christ was born a visible man of a human virgin mother, but he was a hidden God because God was his Father. So the prophet had foretold: "Behold, the virgin shall be with child and shall bring forth a son; and they shall call his name Emmanuel, which is interpreted, God with us." To prove that he was God, Christ worked many miracles, some of which—as many as seemed necessary to establish his claim—are recorded in the Gospels. Of these miracles the very first was the marvelous manner of his birth; the very last, his ascension into heaven in his body risen from the dead. — City of God 18.46
Isaías 7:14
But who shall say that Christ and Christians have no connection with Israel, seeing that Israel was the grandson of Abraham, to whom first, as afterwards to his son Isaac, and then to his grandson Israel himself, that promise was given, which I have already mentioned, namely: "In your seed shall all nations be blessed"? That prediction we see now in its fulfillment in Christ. For it was of this line that the Virgin was born, concerning whom a prophet of the people of Israel and of the God of Israel sang in these terms: "Behold, a virgin shall conceive, and bear a son; and they shall call his name Emmanuel." For by interpretation, Emmanuel means "God with us." This God of Israel … has forbidden the worship of other gods, … has forbidden the making of idols, … has commanded their destruction, … has by his prophet predicted that the Gentiles from the ends of the earth would say, "Surely our fathers have worshiped lying idols, in which there is no profit." This same God is he who, by the name of Christ and by the faith of Christians, has ordered, promised and exhibited the overthrow of all these superstitions. — HARMONY OF THE GOSPELS 1:26
Isaías 7:14
You must appreciate, brothers and sisters, what a tremendous desire possessed the saints of old to see the Christ. They knew he was going to come, and all those who were living devout and blameless lives would say, "Oh, if only that birth may find me still here! Oh, if only I may see with my own eyes what I believe from God's Scriptures!" The saints who knew from the holy Scripture that a virgin was going to give birth as you heard when Isaiah was read: "Behold, a virgin shall conceive in the womb and shall bear a son, and his name shall be called Emmanuel." What Emmanuel means the Gospel declares to us, saying, "which is interpreted, God with us." So do not let it surprise you, unbelieving soul, whoever you are, do not let it strike you as impossible that a virgin should give birth, and in giving birth remain a virgin. Realize that it was God who was born, and you will not be surprised at a virgin giving birth. So then, to prove to you how the saints and just men and women of old longed to see what was granted to this old man Simeon, our Lord Jesus Christ said, when speaking to his disciples, "Many just men and prophets have wished to see what you see and have not seen it; and to hear what you hear and have not heard it." — SERMON 370:3
Isaías 7:14
Do you hesitate or refuse to believe his birth of a virgin, when you ought rather to believe that thus it was fitting for God to be born man? Learn that this, too, was foretold by the prophet: "Behold, a virgin shall conceive and bear a son, and his name shall be called Emmanuel, which is interpreted, God with us." You will not doubt, therefore, the motherhood of a virgin if you want to believe the nativity of a God who does not relinquish the government of the universe and comes in flesh among human beings; who bestows fecundity on his mother yet does not diminish her integrity. — ON FAITH IN THINGS UNSEEN 3:5
