Course 6: The Eucharist: How do Christians know and worship God? The six sessions of Course 6 reveal reasons why the Eucharist is celebrated as a memorial of Christ's saving passion and stands at the very heart of Christian worship. Session 1 looks at worship as communion with God. Session 2 explores the Eucharist as the pattern of all Christian worship. Session 3 looks at the intimacy we have with God in Holy Communion and how we are transformed by the encounter. Sessions 4 - 6 look at worship as a sign and foretaste of heaven, shaping our whole life, and how the whole of life is sacramental.
