Here you may see what great things our theologians of the Sentences[62] have produced. That which is the principal and chief thing, namely, the testament and word of promise, is not treated by one of them; thus they have obliterated faith and the whole power of the mass. But the second part of the mass,--the sign, or sacrament,[63]--this alone do they discuss, yet in such a manner that here too they teach not faith but their preparations and _opera operata_, participations and fruits[64], as though these were the mass, until they have fallen to babbling of transubstantiation and endless other metaphysical quibbles, and have destroyed the proper understanding and use of both sacrament and testament, altogether abolished faith, and caused Christ's people to forget their God, as the prophet says, days without number [Jer. 2:32]. But do you let the others tell over the manifold fruits of hearing mass, and turn hither your mind, and say and believe with the prophet, that God here prepares a table before you, against all those that afflict you, at which your soul may eat and grow fat [Ps. 23:5]. But your faith is fed only with the word of divine promise, for "not in bread alone doth man live, but in every word that proceedeth from the mouth of God." [Deut. 8:3; Matt. 4:4] Hence, in the mass you must above all things pay closest heed to the word of promise, as to your rich banquet, green pasture, and sacred refreshment; you must esteem this word higher than all else, trust in it above all things, and cling firmly to it even through the midst of death and all sins. By thus doing you will attain not merely to those tiny drops and crumbs of "fruits of the mass," which some have superstitiously imagined, but to the very fountainhead of life, which is faith in the word, from which every blessing flows; as it is said in John iv: "He that believeth in me, out of his belly shall flow rivers of living water" [John 7:38]; and again: "He that shall drink of the water that I will give him, it shall become in him a fountain of living water, springing up into life everlasting." [John 4:14][65]
