O Lord, Shepherd of the House of Israel,
 giver of the Law to Moses on Sinai:
 come to rescue us with your mighty power!

The angel of the Lord appeared to Joseph in a dream and said, 
“Joseph, son of David, do not be afraid to take Mary your wife into your home. 
For it is through the Holy Spirit that this child has been conceived in her. 
She will bear a son and you are to name him Jesus, because he will save his people from their sins.” 
When Joseph awoke, he did as the angel of the Lord had commanded him and took his wife into his home.  (Mt 1:18-25)

In Matthew’s gospel, Saint Joseph takes an important role in the Infancy Narrative. Perhaps for all of us, Saint Joseph is a good example of doing what the Lord asks of us. Today we have a popular Christmas Carol in Colombia, Las Barbas de San José (Saint Joseph's Whiskers).
