May is the Month of Mary, but why? For centuries, the Catholic Church has set aside the entire month of May to honor Mary, Mother of God. Not just a day in May, but the entire month. The rosary is probably the best known private devotion in the Catholic Church. Each day in the month of May, MCA students gather together and pray the rosary. We invite all to attend this daily event that is led by our 8th graders at 7:45 am each school day.
