"Angel" means messenger, but the Archangel Gabriel seems to be God's special messenger, particularly of messages concerning Christ. In the Gospel of Luke, Gabriel announces the conception of John the Baptist to his father, Zacharias. Gabriel also announces to Mary God's wish for her to be the bearer of His son. In the Old Testament, Gabriel interprets Daniel's dreams and foretells the coming of the Christ.
St Joseph is a very special, and often overlooked Saint. Adopted father of Jesus and husband to Mary, Joseph was the protector of the Holy Family. Joseph showed mercy to Mary when he didn't understand how she came to be with child. He ensured that Jesus had a safe place to be born, and that Mary and Jesus had a safe place to live their lives.
