Ternio sacrorum theorematum, de uno Deo, de uno mediatore, et de Iesu, qui est Christus

Therefore, just as in the previous recent disputation I acted to show that Augustine, in Epistle 151, pronounced wisely on the method of judging controversies regarding religion when he wrote: "Nothing is to be defined without the authority of Scripture." Likewise: "Scripture prescribes for us the rule of doctrine" (In the book On Wisdom, chapter 1).

So, in this sketch of three principal theorems of sacred theology, I intend only to demonstrate that just as there is one God for us, so too is there one Christ, Intercessor and Savior; and that JESUS, the son of Mary, the God-bearer original: θεοτόκου, is that very same Christ. And therefore, all things that are diametrically original: ἐκ διαμέτρου opposed to these are false.

I confess, however, that I am greatly delighted by this parable: Just as there is one Sun in the sky, which makes other stars shine and illuminates, vivifies, and fosters sublunary things with its light and heat, and were the Sun not there, there would be perpetual night:

So is there one Sun of justice, and the Mediator of God and Men, the man JESUS CHRIST, who illuminates all Saints in the Church with the rays of his wisdom, vivifies them with the blessing of his life, and fosters and preserves them with his grace. He, reigning at the right hand of the eternal Father, also alone intercedes for us, because he alone was crucified for us. And if this Sun had not risen for us, then truly, in darkness and the shadow of death, all would have to wither away and perish.

Since these things are so, is it not greatly to be lamented
