Quoting from Dr. Martin Luther's treatise The Blessed Sacrament of the Holy and True Body of Christ, and the Brotherhoods, written in 1519. God becomes incarnate that we might break His body on a cross, and that same body then be given back to us in the Sacrament of the Altar, healing our bodies and uniting us in perfect love:
Whoever is in despair, distressed by a sin-stricken conscience or terrified by death or carrying some other burden upon his heart, if he would be rid of them all, let him go joyfully to the sacrament of the altar and lay down his woe in the midst of the community [of saints] and seek help from the entire company of the spiritual body—just as a citizen whose property has suffered damage or misfortune at the hands of his enemies makes complaint to his town council and fellow citizens and asks them for help. The immeasurable grace and mercy of God are given us in this sacrament to the end that we might put from us all misery and tribulation [anfechtung] and lay it upon the community [of saints], and especially on Christ. Then we may with joy find strength and comfort, and say, “Though I am a sinner and have fallen, though this or that misfortune has befallen me, nevertheless I will go to the sacrament to receive a sign from God that I have on my side Christ’s righteousness, life, and sufferings, with all holy angels and the blessed in heaven and all pious men on earth. If I die, I am not alone in death; if I suffer, they suffer with me. [I know that] all my misfortune is shared with Christ and the saints, because I have a sure sign of their love toward me.” See, this is the benefit to be derived from this sacrament; this is the use we should make of it. Then the heart cannot but rejoice and be strengthened.
