Perfected through sufferings; refuse two Christs; ‘through whom’ also of Father

On Christ having been sanctified and the priesthood understood concerning him. “For it was fitting for him, for whom are all things and through whom are all things, in bringing many sons to glory, to perfect the pioneer of their salvation through sufferings. For both the one who sanctifies and those who are sanctified are all from one; for which reason he is not ashamed to call them brothers, saying: I will announce your name to my brothers; in the midst of the church I will sing hymns to you.”

Some of the more ignorant, accustomed also to divide the one Lord Jesus Christ into two Christs and into two sons, think that the human from woman — thought on his own and apart from the Word who is from God the Father — is said to be perfected through sufferings, and that he himself is called the pioneer of our salvation, and that he has been perfected by the God-Word himself, given over to suffer as another individually. For they say that “for whom are all things and through whom are all things” fits him most of all, because the blessed evangelist also says: “All things came to be through him, and without him not one thing came to be.” So it was fitting, they say, for the Word — for whom and through whom are all things — in bringing many sons to glory, to perfect through sufferings the pioneer of their salvation, that is, a bare human through the holy virgin. That their account is full of thunderstruck folly I will try to show equally even now. First, “through whom” is also set upon the Father himself. And so the blessed Paul says: “God is faithful, through whom you were called into the fellowship of his Son,” and again: “and if a son, also an heir through God.”
