In a recent Pew survey, two-thirds of Catholics reported that they did not know or believe in the Church's teaching on the Eucharist. Diving into the writings of early doctors and fathers of the Church, and drawing upon his own experience as a scholar of history, practicing Catholic, and former Protestant, Dr. John Sehorn addresses the “mind-boggling” and difficult truth of Jesus' presence in the Blessed Sacrament. It is a truth that confronts us, challenges us, and is one of the greatest gifts that we will ever receive.
