We're now going to talk about the beginnings of one of the most important religions in human history, and even today, the largest religion on Earth, and that, of course, is Christianity. And the central figure in Christianity is Jesus Christ. And the term Christ is given to him, it is Greek for savior, for messiah, because his early followers view him as the prophesied messiah, savior for the Jewish people, and his followers today view him as the savior, the messiah for all humankind. So you have over two billion Christians who view him central to their faith, who view him as their God, but above and beyond that, you also have over a billion Muslims who view him as a significant prophet. Now, just to get some context on the life and times of Jesus, most of the accounts we have of him come from the first four books of the New Testament of the Bible, called the Gospel of Matthew, Gospel of Mark, Gospel of Luke, Gospel of John, sometimes it's the Gospel according to Matthew, Mark, Luke, or John. And the term gospel today often refers to the idea of the life and teaching of Jesus Christ, so you could view it as the life and teaching of Jesus Christ according to Matthew, according to Mark, according to Luke, according to John, but it really comes from Old English for good news. Good news.
