Something to note: several of the quasi-splinter groups such as the Lollards and the Waldensians ended up aligning with Protestants after the Reformation, but many of the documents we have for them come from a point in time after they had been influenced by mainstream Protestant views. Thus, it's not clear what all their beliefs and practices were in earlier times. Clearly, their affiliation indicates they were closer to Protestantism than Catholicism, but they may have been primarily anti-Catholic for various reasons without originally holding to vital Protestant principles.
