The following comes from the fabulous book, A Meal With Jesus.
What are the Christian community’s meals for? They achieve many things. They express so much of God’s grace. They provide a glimpse of what it’s like to live under God’s reign. They express and reinforce the community that Christ has created through the cross. They’re a foretaste of the new creation. They’re a great context in which to invite unbelievers so they encounter the reality of God among us. But they’re not “for” any of these things. It’s a trick question. Everything else—creation, redemption, mission—is “for” this: that we might eat together in the presence of God. God created the world so we might eat with him. The food we consume, the table around which we sit, and the companions gathered with us have as their end our communion with one another and with God. The Israelites were redeemed to eat with God on the mountain, and we’re redeemed for the great messianic banquet that we anticipate when we eat together as a Christian community. We proclaim Christ in mission so that others might hear the invitation to join the feast.
