Last Sabbath, we had Communion at our church. Communion in the Seventh-day Adventist church is a two-fold event (as it was biblically), and this is how we hold Communion. First, comes the foot washing, and second comes the Lord's Supper (grape juice and bread).
"During supper" (John 13:2, 4) Jesus quietly arose, took the servant's towel, poured water into the basin, knelt down, and began to wash the disciples' feet. The Master had become the servant. Understanding the unspoken rebuke, the disciples were filled with shame. When He had completed His work and returned to His place, He said, "If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another's feet. For I have given you an example, that you should do as I have done to you. Truly, truly, I say to you, a servant is not greater than his master; nor is he who is sent greater than he who sent him. If you know these things, blessed are you if you do them." (John 13:14-17)
The ordinance of foot washing and the Lord's supper make up the Communion service. By humbling ourselves and washing each other's feet, we are following Christ's example and coming into the right spirit for Communion.
