Grace flows as we attach ourselves to His goodness. Let's see if we can take some positions on the grace side of the fence. First, many traditions exceed the authority of the Bible, thus victims of tradition abound. When Jesus began communion, his only commands were to do it and to do it to remember him. Some punish people by refusing to offer communion to them, however it should not be refused to anyone who wants to remember Jesus.
Some churches limit administration of communion to special authorities or to special buildings.
Jesus placed no such limitation. Communion belongs to the people, not to the elite. Communion is for anyone who wants to remember and honor Jesus. The very life and action of Jesus proved that. Second, the very act of participating in communion identifies you with the Kingdom of God and symbolizes the continuing forgiveness of sin that Jesus offers.
