If any one affirms that Christ, just like one of the prophets, assumed the perfect man, and refuses to acknowledge that, being begotten in the flesh of the Virgin, He became man and was born in Bethlehem, and was brought up in Nazareth, and advanced in age, and on completing the set number of years (appeared in public and) was baptized in the Jordan, and received this testimony from the Father, “This is my beloved Son,” even as it is written, let him be anathema.
Explication.
How could it be said that Christ (the Lord) assumed the perfect man just like one of the prophets, when He, being the Lord Himself, became man by the incarnation effected through the Virgin? Wherefore it is written, that “the first man was of the earth, earthy.” But whereas he that was formed of the earth returned to the earth, He that became the second man returned to heaven. And so we read of the “first Adam and the last Adam.” And as it is admitted that the second came by the first according to the flesh, for which reason also Christ is called man and the Son of man; so is the witness given that the second is the Savior of the first, for whose sake He came down from heaven. And as the Word came down from heaven, and was made man, and ascended again to heaven, He is on that account said to be the second Adam from heaven.
