December 30, 2012 is the Feast f the Holy Family. The following is excerpted from Catholic Culture:
The Holy Family
Marriage is too often conceived as the sacrament which unites a man and a woman to form a couple. In reality, marriage establishes a family, and its purpose is to increase the number of the elect, through the bodily and spiritual fecundity of the Christian spouses.
1. Every marriage intends children. Although Mary and Joseph were not united in a carnal way, their marriage is a true marriage: an indissoluble, exclusive union, wholly subordinated to the child. Mary and Joseph are united only in order to bring Jesus into the world, to protect and raise him. They have only one child, but he contains the whole of mankind, even as Isaac, an only child, fulfilled the promise made to Abraham of a countless progeny.
2. The purpose of every marriage is to establish a Christian family. The Holy Family observed the religious laws of Israel; it went in pilgrimage to Jerusalem every year with other Jewish families (Lk. 2:41). Jesus saddens and amazes his father and his mother because to their will and company he prefers "to be in his Father's house". Thus it may happen that God's will obliges the family to make disconcerting sacrifices. Yet every Christian family must live in harmony and in prayer, which are the pledges of joy and union.
3. "He remained obedient to them." Jesus was God. And through the fullness of grace Mary stood above Joseph. Nevertheless — if we except the event in the Temple — Joseph remained the head of the family; he took the initiative (as when the Holy Family fled to Egypt), and in Nazareth Jesus obeyed his parents.
