6 But so a difficulty meets us, which we have undertaken to solve in the Name of the Lord, and by His will. If the Father does nothing without the Son, nor the Son without the Father, will it not follow, that we must say that the Father also was born of the Virgin Mary, the Father suffered under Pontius Pilate, the Father rose again and ascended into heaven? God forbid! We do not say this, because we do not believe it. “For I believed, therefore have I spoken: we also believe, and therefore speak.” What is in the Creed? That the Son was born of a Virgin, not the Father. What is in the Creed? That the Son suffered under Pontius Pilate and was dead, not the Father. Have we forgotten, that some, misunderstanding this, are called “Patripassians,” who say that the Father Himself was born of a woman, that the Father Himself suffered, that the Father is the same as the Son, that they are two names, not two things? And these has the Church Catholic separated from the communion of saints, that they might not deceive any, but dispute in separation from her.
