Jesus' Second Coming negates that he's God because God in the Bible promised Noah he'll never destroy the world again, and yet in book of "Revelation" Jesus claims that he'll destroy the world when he comes back, so he wants to break God's promise and only feeble and pathetic non-deities break promises.
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"
