Presence: The Mystery of the Eucharist

This no-cost study and its study guide are available on Just drop in for any session.

This four-part series from Augustine Institute explores the truth and beauty of Christ's Real Presence in the Eucharist, from its origins in Sacred Scripture, to its profound role in the life of the Church and its members. Although the Eucharist appears to be simple bread and wine, it is actually the "source and summit" of the Christian life. It is the crescendo of the entire story of salvation.
