How do we know the Lord's Supper is a biblical ordinance?

The Lord's Supper is biblically grounded as an ordinance instituted by Christ Himself, as recorded in the Gospels, particularly in Luke 22:19-20. This command is carried forward in the New Testament, where the Apostle Paul reaffirms its significance in 1 Corinthians 11, warning believers to observe it with reverence and understanding. The consistency of this practice across early Christian churches signifies its importance, functioning as both a means of remembrance and a proclamation of Christ's death until He returns (1 Corinthians 11:26). The historic practice of the church demonstrates that it is not merely an optional ritual but a vital expression of faith.
