The Lord's Supper, as taught in 1 Corinthians 11, is a solemn proclamation of Christ's death until His return, serving as a vital mark of the true church alongside the pure preaching of the gospel and proper church discipline. Far from being a mere ritual, it is a means of grace that must be subordinate to Scripture, not elevated above it, and is to be observed with self-examination, humility, and love for fellow believers—especially the poor and marginalized. The Corinthian church's failure to discern the Lord's body through division, selfishness, and disregard for the needy reveals how heresy and moral failure distort the sacrament's purpose, leading to spiritual weakness and judgment. True participation requires faith, repentance, and a life marked by Christ-like love, as demonstrated in 1 John 3:16–18, where love is shown in action, not just words. The Lord's Supper, therefore, is not a sacramental magic but a sacred act of remembrance, unity, and ongoing sanctification, pointing believers toward the future feast of the Lamb in God's eternal kingdom.
