[The fourth ecumenical council, the Council of Chalcedon, was held from 8 October to 1 November, 451 AD. Two saints (among hundreds) must be given special thanks for helping bring about the results which the church held to: Cyril of Alexandria and Pope Leo the Great. I will write more about both of these men in the next week. From this council comes perhaps the single most important Patristic statement about Christ]
We confess one and the same Son, who is our Lord Jesus Christ, and we all agree in teaching that this very same Son is complete in his deity and complete — the very same — in his humanity, truly God and truly a human being, this very same one being composed of a rational soul and a body, coessential with the Father as to his deity and coessential with us — the very same one — as to his humanity, being like us in every respect apart from sin. As to his deity, he was born from the Father before the ages, but as to his humanity, the very same one, was born in the last days from the Virgin Mary, the Mother of God, for our sake and the sake of our salvation: one and the same Christ, Son, Lord, Only Begotten, acknowledged to be unconfusedly, unalterably, undividedly, inseparably in two natures, since the difference of the natures is not destroyed because of the union, but on the contrary, the character of each nature is preserved and comes together in one person and one hypostasis, not divided or torn into two persons but one and the same Son and only-begotten God, Logos, Lord Jesus Christ — just as in earlier times the prophets and also the Lord Jesus Christ himself taught us about him, and the symbol of our Fathers transmitted to us.
