[The Lord's Supper teaches that] Rituals are good, and they are instituted and used by God to 'connect' his people with him. We learn through ritual that the church is not just made up of individuals, but is a corporate body. It is not just about personal salvation, but a group of people, the people of God, who are bound to one another and to the faithful through the generations. (page 263)
