Input: Question: Of the two types of Catholicism mentioned, which was founded first? Passage:Luther began by criticising the sale of indulgences, insisting that the Pope had no authority over purgatory and that the Treasury of Merit had no foundation in the Bible. The Reformation developed further to include a distinction between Law and Gospel, a complete reliance on Scripture as the only source of proper doctrine (sola scriptura) and the belief that faith in Jesus is the only way to receive God's pardon for sin (sola fide) rather than good works. Although this is generally considered a Protestant belief, a similar formulation was taught by Molinist and Jansenist Catholics. The priesthood of all believers downplayed the need for saints or priests to serve as mediators, and mandatory clerical celibacy was ended. Simul justus et peccator implied that although people could improve, no one could become good enough to earn forgiveness from God. Sacramental theology was simplified and attempts at imposing Aristotelian epistemology were resisted.
