...from the physical things set forth in the Sacrament we are led by a sort of analogy to spiritual things. Thus, when bread is given as a symbol of Christ’s body, we must at once grasp this comparison: as bread nourishes, sustains, and keeps the life of our body, so Christ’s body is the only food to invigorate and enliven our soul. When we see wine set forth as a symbol of blood, we must reflect on the benefits which wine imparts to the body, and so realize that the same are spiritually imparted to us by Christ’s blood. These benefits are to nourish, refresh, strengthen, and gladden. For if we sufficiently consider what value we have received from the giving of that most holy body and the shedding of that blood, we shall clearly perceive that those qualities of bread and wine are, according to such an analogy, excellently adapted to express those things when they are communicated to us.
