Question-of-Interest: 1) Mt 22:42 - what think ye of Christ? whose son is he? 2) what do these three - John, the young child, and the babe - have in common? From the last time: while visiting Elizabeth and Zacharias, Mary gave birth to her first child, John. Mary left her firstborn son, John, with Elizabeth and Zacharias. We learned that Jesus in not Mary's firstborn child; Jesus is not Mary's firstborn son.
