"12] First, purgatory. Here they carried their trade into purgatory by masses for souls, and vigils, and weekly, monthly, and yearly celebrations of obsequies, and finally by the Common Week and All Souls Day, by soul-baths so that the Mass is used almost alone for the dead, although Christ has instituted the Sacrament alone for the living. Therefore purgatory, and every solemnity, rite, and commerce connected with it, is to be regarded as nothing but a specter of the devil. For it conflicts with the chief article [which teaches] that only Christ, and not the works of men, are to help [set free] souls. Not to mention the fact that nothing has been [divinely] commanded or enjoined upon us concerning the dead. Therefore all this may be safely omitted, even if it were no error and idolatry. 
13] The Papists quote here Augustine and some of the Fathers who are said to have written concerning purgatory, and they think that we do not understand for what purpose and to what end they spoke as they did. St. Augustine does not write that there is a purgatory nor has he a testimony of Scripture to constrain him thereto, but he leaves it in doubt whether there is one, and says that his mother asked to be remembered at the altar or Sacrament. Now, all this is indeed nothing but the devotion of men, and that, too, of individuals, and does not establish an article of faith, which is the prerogative of God alone. 
14] Our Papists, however, cite such statements [opinions] of men in order that men should believe in their horrible, blasphemous, and cursed traffic in masses for souls in purgatory [or in sacrifices for the dead and oblations], etc. But they will never prove these things from Augustine. Now, when they have abolished the traffic in masses for purgatory, of which Augustine never dreamt, we will then discuss with them whether the expressions of Augustine without Scripture [being without the warrant of the Word] are to be admitted, and whether the dead should be remembered at the Eucharist. 15] For it will not do to frame articles of faith from the works or words of the holy Fathers; otherwise their kind of fare, of garments, of house, etc., would have to become an article of faith, as was done with relics. [We have, however, another rule, namely] The rule is: The Word of God shall establish articles of faith, and no one else, not even an angel."
