From Eucharist to Euangelion
This cuts both ways. Our Eucharistic liturgy is obviously shaped by our soteriology, but our soteriology is shaped by our Eucharistic liturgy as well. So if we want people to have a clearer grasp of (say) union with Christ, it will help us if we stress the (present) communion with Jesus as we break bread, not just the (past) forgiveness of sins. If we want people to grasp the hope of resurrection, it will help us if we find ways to emphasise the ways in which Supper is a foretaste of the (future) eschatological banquet; if, that is, we hear 1 Corinthians 11:26 as often as 11:25.
The Lord’s Supper is a meal of remembrance, communion and hope (hence his title). If, as Billings suggests, “many congregations have blind spots” to two of these three themes, then reworking our practice of Communion to help us see them, and even taste them, would surely be a good idea.
