Both baptism and the Lord’s Supper are ordinances that remind us of Jesus’ grace shown in His life, death, and resurrection. Because we rejoice in His forgiveness and accept His salvation, we are eager to publicly demonstrate our commitment to Him in baptism by immersion (see Step #15, Baptism) as well as participation in the Lord’s Supper. As baptism precedes church membership, so the foot washing precedes partaking of the symbols of Christ’s sacrifice on Calvary. JTL26 10.1
Baptism binds us to Christ in His death; the Lord’s Supper is the proclamation of our Lord’s death and resurrection until His second advent. The believer is baptized into Christ and the fellowship of His church; believers experience strong ties of Christian confession, fellowship, and unity at the communion service. This ordinance is a God-given opportunity to reflect on one’s baptismal vows. JTL26 10.2
