Ambrose of Milan : But He, although He took on Him our flesh, although He was made man that He might redeem man, and recal him from death, still, as being God, came upon earth in an extraordinary way, that as He had said, 'Behold I make all things new,' so also He might be born of an immaculate virgin, and be believed to be, as it is written, 'God with us.' But from their perverse ways they are induced to say 'She was a virgin when she conceived, but not a virgin when she brought forth.' Could she then conceive as a virgin, and yet not be able to bring forth as a virgin, when conception always precedes, and birth follows? — Letter 42, To Pope Siricius Clement of Alexandria : The Word says, "Look, I am doing something new, which no eye has seen, no ear heard, no human heart felt." These are to be seen, heard and grasped by a new eye, a new hearing and a new heart when the Lord's disciples speak, listen and act in the Spirit. — The Stromata Book 2 Cyprian : But as often as water is named alone in the holy Scriptures, baptism is referred to, as we see intimated in Isaiah: "Remember not," says he, "the former things, and consider not the things of old. Behold, I will do a new thing.…" There God foretold by the prophet that among the nations, in places that previously had been dry, rivers should afterwards flow plenteously and should provide water for the elected people of God, that is, for those who were made children of God by the generation of baptism. Moreover, it is again predicted and foretold before, that the Jews, if they should thirst and seek after Christ, should drink with us, that is, should attain the grace of baptism. "If they shall thirst," he says, "he shall lead them through the deserts, shall bring forth water for them out of the rock. The rock shall be cloven, and the water shall flow, and my people shall drink," which is fulfilled in the Gospel, when Christ, who is the Rock, is cloven by a stroke of the spear in his passion; who also, admonishing what was before announced by the prophet, cries and says, "If anyone thirst, let him come and drink. He who believes in me, as the Scripture says, out of his belly shall flow rivers of living water." And that it might be more evident that the Lord is speaking there not of the cup but of baptism, the Scripture adds, saying, "But this spoke he of the Spirit, which they that believe in him should receive." For by baptism the Holy Spirit is received, and thus by those who are baptized and have attained to the Holy Spirit is attained the drinking of the Lord's cup. — Epistle LXII:8 Tertullian : For of this number I find figurative hints up and down the Creator's dispensation in the twelve streams of Elim. … Now the same number of apostles was thus portended, as if they were to be fountains and rivers that should water the Gentile world, which was formerly dry and destitute of knowledge, as he says by Isaiah, "I will put streams in the unwatered ground." — AGAINST MARCION 4.13 Theodoret of Cyrus : What I am going to do, he says, merits still more admiration than the things done [in the past]. He adds what will be: "And I will make a way in the wilderness and rivers in the dry land." Some have thought that these declarations relate to the return from Babylon. This is wrong, for he did not favor them at that time, while they were returning from exile, either with a strange road or with rivers. But he is calling the Gentiles "the desert" [wilderness], and the preachings of the apostles "rivers" and the course that escapes error "the way." What he has added makes it equally obvious. — COMMENTARY ON Isaiah 13:43.19 Theodoret of Cyrus : "Because I have given water in the wilderness and rivers in the waterless land to assuage the thirst of my elect race; the people I have set aside for myself proclaim my virtues." The race that [Jesus] put on according to his human nature is human nature in its entirety, yet is nearer still to the Jewish race. For there is no doubting that our Lord came from Judah. — COMMENTARY ON Isaiah 13:43.21
