Luther gem from 1539

See that you exercise and confirm your faith, so that when you are troubled or when sin is besetting you, you go to the Sacrament and heartily desire it, and what it signifies, and do not doubt that it will be done unto you as the Sacrament declares, that Christ and all His saints will draw near to you with all their virtues, sufferings, and graces, to live, work, rest, suffer and die with you, and be so fully yours that they have all things in common with you. If you are willing to practice this belief and confirm it, you will experience what a rich and joyful wedding-meal your God has prepared for you on the altar.—from On the Councils and Churches, 1539
