Dr. Accetta was raised Catholic attending Mass every Sunday and praying the Rosary every day. In Medical School, he stopped practicing his faith and became an agnostic. While in residence he met his wife who was a devout Evangelical Protestant. His return to faith began with an interest in the medical evidence in the Shroud of Turin. He became so interested that he opened the Shroud of Turin Center of Southern California. Though he was again a Christian, for a time he was a Fundamentalist Protestant. A study of history and theology eventually led him back Home to the Catholic Church.
