Peter Waldo
In 1179, Waldo and one of his followers went to Rome, where they were welcomed by Pope Alexander III, and the Roman Curia. They had to explain what they believed in front of a panel of three clergymen, including issues which were then debated within the Church. These included the idea that all people were priests, teaching the gospel in the language most people spoke, and people living poor, simple lives on purpose. The results of the meeting were inconclusive, and Waldo's ideas, but not the movement itself, were condemned at the Third Lateran Council in the same year, although the leaders of the movement had not been yet excommunicated (kicked out of the Church).
