“And lest it should be wearisome to go through all the heresies, and to enumerate either the follies or the madness of each of them, because it is no pleasure to speak of that which one either dreads or is ashamed to know, let us examine in the meantime about Marcion alone. the mention of whom has ben made in the letter transmitted by you to us, whether the ground of his baptism can be made good. For the Lord after His resurrection, sending His disciples, instructed and taught them in what manner they ought to baptize, saying, ‘All power is given unto me in heaven and in earth. Go ye, therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.’ He suggests the Trinity, in whose sacrament the nations were to be baptized. Does Marcion then maintain the Trinity? Does he then assert the same Father, the Creator, as we do? Does he know the same Son, Christ born of the Virgin Mary, who as the Word was made flesh, who bare our sins, who conquered death by dying, who by Himself first of all originated the resurrection of the flesh, and showed to His disciples that He had risen in the same flesh? Widely different is the faith with Marcion, and moreover, with the other heretics; nay, with them there is nothing but perfidy, and blasphemy, and contention, which is hostile to holiness and truth. How then can one who is baptized among them seem to have obtained remission of sins, and the grace of the divine mercy, by his faith, when he has not the truth of the faith itself? “
