From the back of the card:

"While the aged Jewish priest was performing his duties in the Temple of Jerusalem, an angel appeared to him saying, "Zachary, do not be afraid; your prayer has been heard, and your wife Elizabeth is to bear a son to whom you shall give the name of John."  The angel told Zachary that his son would be filled with the Holy Spirit in his mother's womb and would bring many Israelites back to God...  Zachary's feast day is November 5th."
