Communion is what brings us together as a body of believers. It is the meal taken as the congregation comes together to remember Christ’s body that was broken for us (bread) and His blood that was spilled for us (juice). We believe that communion is only for those who are members of the body (saved, baptized, committed to a local church), and should not be partaken by those who have not yet surrendered their lives to Jesus Christ. This sacred time should be used for believers to repent of sins, reflect on the grace of God, and rejoice together as a redeemed people.

For I tell you that from now on I will not drink of the fruit of the vine until the kingdom of God comes.” And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant in my blood.
— Luke 22:18-20
The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread. Consider the people of Israel: are not those who eat the sacrifices participants in the altar? What do I imply then? That food offered to idols is anything, or that an idol is anything?
— 1 Corinthians 10:16-19
For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.
— 1 Corinthians 11:26
