So then, when you come to the Lord’s Supper to feed spiritually upon Christ, and when you thank the Lord for his great favour, for the redemption whereby you are delivered from despair, and for the pledge whereby you are assured of eternal salvation, when you join with your brethren in partaking of the bread and wine which are the tokens of the body of Christ, then in the true sense of the word you eat him sacramentally. You do inwardly that which you represent outwardly, your soul being strengthened by the faith which you attest in the tokens.
