From the red-letter part of Scripture:

“I tell you, among those born of women none is greater than John. Yet the one who is least in the kingdom of God is greater than he.” (Luke 7:28)

Unless Mary was not born of a woman — a whole new meaning to immaculate conception — Jesus’ words would seem to rank John the Baptist higher than the Virgin Mary.

Calvin comments:

Accordingly, Christ extols and places him above the rank of the prophets, and gives the people to understand that he had received a special and more excellent commission. When he elsewhere says respecting himself that he was not a Prophet, (John 1:21,) this is not inconsistent with the designation here bestowed upon him by Christ. He was, no doubt, a Prophet, like others whom God had appointed in his Church to be expounders of the Law, and messengers of his will; but he was more excellent than the Prophets in this respect, that he did not, like them, make known redemption at a distance and obscurely under shadows, but proclaimed that the time of redemption was now manifest and at hand. Such too is the import of Malachi’s prediction, (Malachi 3:1,) which is immediately added, that the pre-eminence of John consisted in his being the herald and forerunner of Christ; for although the ancient Prophets spoke of his kingdom, they were not, like John, placed before his face, to point him out as present. As to the other parts of the passage, the reader may consult what has been said on the first chapter of Luke’s Gospel.

Had Jesus forgotten his mother?
