The month of May presents American Catholics with mixed martial messages. On May 12, we celebrated the Saints Nereus and Achilleus, Roman soldiers who left the army after their conversion to Christianity. Yesterday, we joined other Americans in celebrating Memorial Day, which honors those who gave their lives defending a country with no established church and no official religion. And on May 13th we celebrated the 1917 apparition of the Blessed Virgin Mary at Fatima, in Portugal – a message of peace in the midst of World War I. These mixed messages reflect tensions present in the Church from its beginning. Dr. Christopher Shannon joins us.
