How do we know that the Lord's Supper is a commandment from Jesus?

Jesus instituted the Lord's Supper with the clear instruction to His disciples to observes it 'in remembrance of me.' This command is foundational, as recorded in 1 Corinthians 11:24-25, wherein the Apostle Paul recounts the events of the Last Supper. The authoritative nature of this command emphasizes the significance of the Supper; it is not merely a ritual but an essential practice for the church. The tradition of partaking in the Lord's Supper has continued throughout church history, reaffirming its status as a divine command that is to be followed until Jesus returns. This obedience to Christ's teaching underlines the unity of the body of Christ as they collectively remember His sacrifice.
