Does the Lord’s Supper add anything to Christ’s atoning work?
No, Christ died once for all. The Lord’s Supper is a covenant meal celebrating Christ’s atoning work; as it is also a means of strengthening our faith as we look to him, and a foretaste of the future feast. But those who take part with unrepentant hearts eat and drink judgment on themselves.
(New City Catechism)
The feast awaits.
Now symbols and nutrients are divided,
vying for space in our minds.
The stomach craves what cannot sate spirit;
vine recalls dirt, bread anticipates yeast –
the work is done, the meal yet to be.
Take and eat. Eat and drink.
Bread cannot do what Spirit’s not done;
what bakes without yeast cannot rise.
Eat, recall; drink and trust:
what’s done has been done
and will prove true
when symbol and food can be one.
