I’ve written a short blog piece at Bible Study and the Christian Life on what happens at the Lord’s Supper. It builds off the Last Supper as a redefinition of the Passover, and uses a modern analogy to help us think correctly about it. Note, by definition no analogy is perfect. If it were, it would be the thing to which it’s trying to point. So there are limitations to the analogy I use, but I hope it gets us thinking in the right direction.
