The Most Chaste Heart of St. Joseph is a devotion to the foster-father of Jesus Christ. In Catholic tradition, Wednesday is the day of the week devoted to St. Joseph. The official prayers for the devotion to The Most Chaste Heart of Joseph is the Chaplet of the Seven Sorrows and Seven Joys to St. Joseph. This devotion does not have a liturgical veneration the way that Jesus and Mary do. But, it is still a beautiful devotion that is supported by many saints, including Doctors of the Church.
