What does the Bible say about baptism and the Lord's Supper?

According to the Goat Yard Declaration, baptism and the Lord’s Supper are essential ordinances established by Jesus. Baptism, serving as a public profession of faith, signifies the believer's identification with Christ's death, burial, and resurrection, as seen in Matthew 28:19. The Lord’s Supper, on the other hand, is a continual remembrance of Christ's sacrifice, wherein believers partake of bread and the cup as symbols of His body and blood, affirming their covenant relationship with Him. Both ordinances are vital for the church community, representing outward expressions of inward faith and indicators of the believer’s ongoing participation in the life of the church as they await Christ’s return.
