“Thus we should be bold and say that while the Gospels are the firstfruits of Scripture as a whole, the firstfruits of the Gospels is the Gospel of John, whose profound meaning cannot be perceived except by him who rested his head on Jesus’ breast and who received Mary to be his mother also.
He who wishes to be another John must become as in order to be pointed out by Jesus as another John, that is to say, another Jesus. While Mary has no son other than Jesus, as it appears to those who think correctly about her, nevertheless Jesus said to his Mother, “Behold you son” (Jn 19:26), and not, “Behold, this man also is your son.” in other words, he said to her. “This man is Jesus, whom you bore.”
Indeed, when someone is perfect, it is no longer he that lives, but Christ lives in him (cf. Gal 2:20); therefore when he speaks of him to Mary, he says, “Behold your son, that is, Jesus Christ.”Origen, Commentary on John 1:6; PG 14:32
