Marco Dimitri - "the most famous Satanist in Europe." But he was actually a critic of the Catholic Church. He was also known for saying that Satanism is not about worshiping evil, rather it is a symbol of being an adversary, standing up to a repressive system. He was also accused and jailed many times for false crimes he did not commit, and was thus exonerated.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
