The Eucharist and the Cross are still stumbling blocks today, just as they were in the gospel accounts. Yet these stumbling blocks are the key to our faith because the Eucharist is the Real Presence of Christ himself. From the beginning of Christianity, the belief in the Eucharist has been at the core of the Christian faith. Bishop Cozzens explains a proper Catholic understanding of the Eucharist, drawing on the fundamental teachings of the Catholic faith and aspects of the liturgy, church history, and so on.
