Disputation of the First Day
Fortunatus said: If with regard to the soul the apostle had said that we are by nature children of wrath, the soul would have been alienated by the mouth of the apostle from God. From this argument you only show that the soul does not belong to God, because, the apostle says, "We are by nature children of wrath." But if it is said in view of the fact that the apostle was held by the law, descending as he himself testifies, from the seed of Abraham, it follows that he has said corporeally, that we [i.e., Jews] were children of wrath even as the rest of mankind. But he shows that the substance of the soul is of God, and that the soul cannot otherwise be reconciled to God than through the Master, who is Christ Jesus. For the enmity having been slain, the soul seemed to God unworthy to have existed. But that it was sent, this we confess, by God yet omnipotent, both deriving its origin from Him and sent for the sealing of His will. In the same way we believe also that Christ the Saviour came from heaven to fulfill the will of the Father. Which will of the Father was this, to free our souls from the same enmity, this enmity having been slain, which if it had not been opposed to God could neither be called enmity where there was unity, nor could slaying be spoken of or take place where there was life.
18. Augustine said: Remember that the apostle said that we are alienated from God by our manner of life.
Fortunatus said: I submit, that there were two substances. In the substance of light, as we have above said, God is to be held incorruptible; but that there was a contrary nature of darkness, that which I also today confess is vanquished by the power of God, and that Christ has been sent forth as a Saviour for my restoration, as previously the same apostle says.
19. Augustine said: That we should discuss on rational grounds the belief in two natures, has been made obligatory by those who are hearing us. But inasmuch as you have again betaken yourself to the Scriptures, I descend to them, and demand that nothing be passed by, lest using certain statements we should bring confusion into the minds of those to whom the Scriptures are not well known. Let us therefore consider a statement that the apostle has in his epistle to the Romans. For on the first page is what is strongly against you. For he says: "Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God, which He promised aforetime by His prophets in the Holy Scriptures, concerning his Son, who was made unto Him of the seed of David according to the flesh, who was predestinated to be the Son of God with power, according to the spirit of holiness from the resurrection from the dead of our Lord Jesus Christ." We see that the apostle teaches us concerning our Lord Jesus Christ that before the flesh he was predestinated by the power of God, and according to the flesh was made unto Him of the seed of David. Since you have always denied and always will deny this, how do you so earnestly demand the Scriptures that we should discuss rather according to them.
Fortunatus said: You assert that according to the flesh Christ was of the seed of David, when it should be asserted that he was born of a virgin, and should be magnified as Son of God. For this cannot be, unless as what is from spirit may be held to be spirit, so also what is from flesh may be known to be flesh. Against which is the authority of the Gospel in which it is said, that "flesh and blood shall not inherit the kingdom of God, neither shall corruption inherit incorruption."
Here a clamor was made by the audience who wished the argument to be conducted on rational grounds, because they saw that Fortunatus was not willing to receive all things that are written in the Codex of the apostle. Then little discussions began to be held here and there by all, until Fortunatus said that the Word of God has been fettered in the race of darkness. At which, when those present had expressed their horror, the meeting was closed.
