In a fallen world it is possible to mess just about anything up, including the good things. That said, there are some things that can help us mess up less.
The weekly celebration of the Lord’s Supper could get messed up. It could become stale ritual, a heartless motion-going. Worse, it could become a source of self-righteousness and superiority over others who don’t do it as often or who use grape juice or tiny, dry cracker bits.
But you really have to work to not think about what we’re doing here to get to that point. It doesn’t take much remembrance to promote humility and relationship.
The reason for the bread and the wine is because of our sin. Jesus gave His body and His blood because we rebelled against God and God requires atonement. We remember what we deserved, and we remember that salvation came from outside of us and by grace to us. That is humbling.
The goal of salvation, though, is not that we be humbled, but that we be exalted by Him rather than exalted by self-attempt and self-promotion. The Lord’s Supper is a time for our communion with the Father through the Son by the Spirit. That is relationship with the Trinity, and relationship with others in the Body in reflection of the Trinity.
More than facts, more than truth, we know God’s love, and that feeds our love for Him and each other.
