On the Incarnation of the Lord, Against Nestorius

Therefore since we have, as I fancy, already in all the former books with the weight of sacred testimonies, given a complete answer to the heretic who denies God, now let us come to the faith of the Creed of Antioch and its value. For as he was himself baptized and regenerated in this, he ought to be confuted by his own profession, and (so to speak) to be crushed beneath the weight of his own arms, for this is the method, that as he is already convicted by the evidence of holy Scripture, so now he may be convicted by evidence out of his own mouth. Nor will there be any need to bring anything else to bear against him when he has clearly and plainly convicted himself. The text then and the faith of the Creed of Antioch is this. “I believe in one and the only true God, the Father Almighty, Maker of all things visible and invisible. And in one Lord Jesus Christ, His only begotten Son, and the first-born of every creature, begotten of Him before all worlds, and not made: Very God of Very God, Being of one substance with the Father: By whom both the worlds were framed, and all things were made. Who for us came, and was born of the Virgin Mary, and was crucified under Pontius Pilate and was buried: and the third day He rose again according to the Scripture: and ascended into heaven, and shall come again to judge the quick and the dead,” etc. In the Creed which gives the faith of all the Churches, I should like to know which you would rather follow, the authority of men or of God? Though I would not press hardly or unkindly upon you, but give the opportunity of choosing whichever alternative you please, that accepting one, I may deny the other: for I will grant you and yield to you either of them. And what do I grant, I ask? I will force you to one or other even against your will. For you ought, if you like, to understand of your own free will that one or other of these is in the Creed: if you don’t like it, you must be forced against your will to see it. For, as you know, a Creed (Symbolum) gets its name from being a “collection.” For what is called in Greek σύμβολος is termed in Latin “Collatio.” But it is therefore a collection (collatio) because when the faith of the whole Catholic law was collected together by the apostles of the Lord, all those matters which are spread over the whole body of the sacred writings with immense fulness of detail, were collected together in sum in the matchless brevity of the Creed, according to the Apostle’s words: “Completing His word, and cutting it short in righteousness: because a short word shall the Lord make upon the earth.” This then is the “short word” which the Lord made, collecting together in few words the faith of both of His Testaments, and including in a few brief clauses the drift of all the Scriptures, building up His own out of His own, and giving the force of the whole law in a most compendious and brief formula. Providing in this, like a most tender father, for the carelessness and ignorance of some of his children, that no mind however simple and ignorant might have any trouble over what could so easily be retained in the memory.
