'Of course, the first time Christ uttered the word ‘Abba’ on this earth, he was likely looking into the eyes of St. Joseph, which is a point that is worthy of mention. God the Father could have chosen to allow the Blessed Virgin to live and work as a single mother. He could have given her a couple of extra guardian angels or sent Elizabeth to care for her. He is the God who created the giraffe, the coffee bean, and cumulus clouds. He does not suffer from a lack of creativity or specificity in his providence, design, or problem solving.
Some suggest that God only had St. Joseph as part of the Holy Family because of cultural expectations, but that is dangerously presumptuous. This is a God who constantly laughs (Psalm 2:4) in the face of social norms. St. Joseph is not window-dressing in the home of the Holy Family; he is nothing less than one of the greatest men to ever walk the planet. A model of manhood and virtue, God the Father specifically called and designed Joseph to be the living embodiment of manhood and fatherhood to the second Person of the Holy Trinity during his most formative years.
In St. Joseph, then, we're given a glimpse into the heart of God the Father. It would be completely illogical to think, after all the trouble of the incarnation, that he would fail to choose a man who reflected his divine image of paternal love with the highest possible measure of human faithfulness.'
