Like Baptism, Communion is a sacred practice that Jesus instructs His followers to partake in.
At its most basic level, Communion is the joyous practice of taking bread and grape juice as memorial of what Jesus endured on the cross for mankind, of our present relationship with him, and of our victory over sin and death.
The practice of Communion was first established by Jesus during a meal with his disciples on the first day of the Festival of Unleavened Bread or Passover.
"While they were eating, Jesus took some bread, and after a blessing, He broke it and gave it to the disciples, and said, “Take, eat; this is My body.” And when He had taken a cup and given thanks, He gave it to them, saying, “Drink from it, all of you; for this is My blood of the covenant, which is poured out for many for forgiveness of sins. But I say to you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in My Father’s kingdom.” —Matthew 26:26–29
The frequency of Communion varies from church to church. But we typically participate in Communion on the 1st Sunday of each month.
