We should not think of the Eucharist not so much as Christmas—as if the Son were born again in bread—but instead think about it instead in terms of Advent. This table marks a triple Advent: It celebrates the past coming of the Lord; it is the coming of the Lord; and it looks ahead to the coming of the Lord. We commemorate the life, death and resurrection of Jesus; we feed on Him by the Spirit; we proclaim the Lord’s death until He come.
When we view it as an Advent meal, we see that this Supper is about Jesus’ absence as well as His presence; it’s about the future as well as the present. It is a present feast, a feast we celebrate because the Lord has come. But it is not yet a full banquet, because the Lord is still to come.
