Dr. Paul Farmer - there is a famous book that describes his life work:
Quote:Mountains Beyond Mountains takes us from Harvard to Haiti, Peru, Cuba, and Russia as Farmer changes minds and practices through his dedication to the philosophy that "the only real nation is humanity"—a philosophy that is embodied in the small public charity he founded, Partners in Health. He enlists the help of the Gates Foundation, George Soros, the U.N.’s World Health Organization, and others in his quest to cure the world.
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"
