The Waldensians and the Albigensians a)were declared heretics and persecuted by the Catholic Church. The Waldensians believe in apostilic poverty (which means no ownership of lands or accumulation of money), believed that every Church should be independent in how it is run and did not venerate sacred events such as the Last Supper. The Albigensians thought that there was an evil God and a good God, which goes against the Catholic Church's belief that there is only one God.
