Pope Francis continued his catechesis series on St. Joseph at the weekly General Audience of December 29, 2021, focusing on his role as "a persecuted and courageous migrant." Following the depiction of Jesus' foster father in the Gospel of Matthew (2:13-23), the Pope explored the massacre of all children under the age of 2 in Bethlehem, ordered by King Herod after the visit of the Magi.
