As quoted in Bernhard Lohse’s, Martin Luther’s Theology: Its Historical and Systematic Development:
For just as the bread is made out of many grains ground and mixed together, and out of the bodies of many grains there comes the body of one bread, in which each grain loses its form and body and takes upon itself the common body of the bread . . . so it is and should be with us, if we use this sacrament properly. Christ with all saints, by his love, takes upon himself our form [Phil. 2:7], fights with us against sin, death, and all evil. . . . Again through this same love, we are to be changed and to make the infirmities of all other Christians our own; we are to take upon ourselves their form and their necessity, and all the good that is within our power we are to make theirs. . . . In this way we are changed into one another and are made into a community by love. Without love there can be no such change. || Martin Luther, Luther’s Works vol. 35, p. 58.
