We Christians should... cherish this Testament as a treasure of the highest value, should love it dearly, and should make use of it cheerfully and frequently, deriving from it much joy and consolation, thus fulfilling the will of our dying Lord and Savior. His command in this regard is plain; He urges upon us the use of this Sacrament. True Christians will never disregard this command, but will readily and often find comfort in its fulfillment, even until that day when the Lord, who Himself gave us such a Testament, shall again come from heaven to judge the living and the dead. (Martin Luther, Maundy Thursday Sermon)
