Here is a homily I gave to our monks in 2015 summarizing the interpretations of St. Joseph’s “doubt” in chapter 1 of Matthew’s Gospel. There are three main approaches to St Joseph’s struggle by saints, doctors, theologians and Popes throughout the ages. All three approaches can help us to see the greatness of this man chosen by God to be the spouse of Mary and the human, virginal father (legally, socially, but not biologically) of Jesus, the Son of God.
St Joseph, son of David, pray for us!
