The Communion Ministry prepares the communion for each worship service that it is observed.
The purpose of partaking in communion for Christians is in remembrance of Jesus Christ and the sacrifices that he made on our behalf. It is also a way for us to become one with Christ.
1 Corintians 11:23-26 (NIV)
For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.” For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.
