We celebrate communion or the Lord's Supper (or Eucharist in some traditions) at Peace on the first Sunday of each month and at our annual Good Friday service. All communing members of gospel-believing churches are invited to participate with us.
Now as they were eating, Jesus took bread, and after blessing it broke it and gave it to the disciples, and said, “Take, eat; this is my body.” And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. Jesus in Matthew 26:26-28.
The Westminster Shorter Catechism Q & A 96 describes the Lord's Supper in this way:
Q: What is the Lord's Supper?
A: The Lord’s Supper is a sacrament in which, by giving and receiving bread and wine according to Christ’s appointment, his death is proclaimed, and those who receive rightly are by faith (and not by the mouth in a physical manner) made partakers of his body and blood, with all his benefits, to their spiritual nourishment and growth in grace.
Question and Answer 97
Q: What is required to receive rightly the Lord's Supper?
A: It is required of those who would receive rightly the Lord’s Supper, that they examine themselves as to their knowledge of the meaning and object of this sacrament, their faith to feed upon Christ, and their repentance, love and new obedience; for coming in an unworthy manner would bring judgement on themselves.
