And so for the most part they seem to have learned only these things from the gospel of Christ: first to reject the tyranny of the Roman Antichrist and the false bishops.  Next, to throw off the yoke of any kind of discipline, penitence, and universal religion which was left in the papacy, and establish and do all things according to the desire and whim of their flesh. Thus it was not displeasing to them to hear that we are justified by faith and not by good works, in which they had no interest. They never seriously considered what was explained to them about the nature and power of true faith in Christ, and how necessary it is to be prolific in good works.  A number of them accepted some preaching of the gospel only in order that they might confiscate the rich properties of the Church.
