When we're already talking about silver linings in terrorism toward Jews it was actually on this day in 1965 that the Second Vatican Council voted to absolve Jews of responsibility for the death of Jesus, a responsibility placed upon them for 760 years.
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"
