For instance, if I were to say: “Wittenberg beer quenches the thirst, but Annaberg beer does so too,” I would not be excluding any other beer from doing the same thing. But matters change if I say: “If you do not drink Wittenberg beer, you will find no other beer to slake your thirst.” Thus Christ does not confine Himself here to an affirmative statement, but He excludes everything else as He says: “Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.” Thus he who despises His flesh will find that nothing else will prove helpful or be accounted valid. I may call on St. Mary or St. Peter, but they cannot help. All else is ruled out completely. In brief, all other methods are rejected.
Martin… beer is hardly a fit illustration for the uniqueness of Christ’s sacrifice. You German sot.
