Marian Chivalry

The unborn John the Baptist bows before the unborn Jesus. Such depiction appears only in three more churches in Cyprus.

What can only be described as definitive and categorical for those who adhere to the canonical veracity of the New Testament, Luke 1:41ff describes an in utero meeting between two extremely important persons:

When Elizabeth heard Mary's greeting, the infant leaped in her womb, and Elizabeth, filled with the holy Spirit, cried out in a loud voice and said, "Most blessed are you among women, and blessed is the fruit of your womb. And how does this happen to me, that the mother of my Lord should come to me? For at the moment the sound of your greeting reached my ears, the infant in my womb leaped for joy. Blessed are you who believed that what was spoken to you by the Lord would be fulfilled."

This should be quite sufficient for anyone at all interested in Marian chivalry: to be on the side of the angels; to settle any debate about the inestimable worth of unborn persons; and to take up the staff, sword, helm, and mantel with us at Corpus Christianum.
