This room is where sinners made saints gather to eat a holy meal because they have been made holy by a holy God. This room is where man has been reconciled to God through the death, burial and resurrection of Jesus. We have died in Him. We have been raised in Him. We live with Him.
This room is where sinners before God and sinners against one another have been reconciled with one another. Thus, the members of this room are one in Christ Jesus. This is no room for division for in this room there is no room for division.
