Therefore the mass and this sacrament are a sign by which we train and accustom ourselves to let go all visible love, help, and comfort, and to trust in Christ and in the invisible love, help, and comfort of His saints. For death takes away everything visible, and separates us from men and temporal things; hence, to meet death, we must have the help of the invisible and eternal things; and these are indicated to us in the sacrament and sign, to which we cling by faith, until we attain to them also by sight. Thus the sacrament is or us a ford, a bridge, a door, a ship, and a litter, in which and by which we pass from this world into eternal life. Therefore all depends on faith. He who does not believe is like one who must cross the sea, but is so timid that he does not trust the ship; and so he must remain and never be saved, because he does not embark and cross over. This is due to our dependence on the senses and to our untried faith which shrinks from the passage across the Jordan of death--the devil also cruelly helps toward this. 22. This was indicated of old in Joshua iii [Josh. 3:7 ff.]. After the children of Israel had gone dry-shod through the Red Sea, a type of baptism, they went through Jordan in like manner; but the priests stood with the ark in Jordan, and the water below them lowed by, while that above them stood upon a heap, a type of this sacrament. The priests carry and uphold the ark in Jordan when in the hour of our death or peril they preach and administer to us this sacrament, Christ, and the fellowship of all saints. I we believe, the waters below us depart, that is, the temporal, visible things harm us not, but flee from us. And those above us stand up high, as though they would overwhelm us; these are the horrors and apparitions of the other world, which at the hour of death terrify us. If, however, we pay no heed to them, and pass on with a firm faith, we shall enter into eternal life dry-shod and unharmed. We have, therefore, two principal sacraments in the church, baptism and the bread. Baptism leads us into a new life on earth; the bread guides us through death into eternal life. And the two are typified by the Red Sea and the Jordan, and by the two lands, one beyond and one on this side the Jordan. Therefore our Lord said at the Last Supper: "I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in My Father's kingdom." [Matt. 26:29] So entirely is this sacrament intended and ordained to strengthen us against death, and to give us entrance into eternal life.
