Ha! The "Jesus striking a kid dead" comes from "The Gospel of Thomas," a writing about Jesus that no one takes seriously. Like we say, "Just because it's on TV doesn't mean it's true." Just because some goofball wrote it down doesn't mean it's so. No one acknowledges the historicity of these stories. There are lots of other "gospels" out there. There a gospel of Judas. blah blah blah. Interesting fiction, but not history. They are stories of Jesus as a kid, but they're fictional.

And in answer to the other comment, there are no sections of the Bible that were taken out. The New Testament was affirmed in 367 AD with the 27 books we still have in it. No books were ever taken out. In 1546 at The Council of Trent, after Luther split off from the Catholic Church, the Catholics added what we call the Apocrypha—in the neighborhood of a dozen books. Some Catholics say that the Council of Trent affirmed those books back in the 4th and 5th century under Augustine, but the truth is that those books were always in dispute, especially in a dispute between Jerome and Augustine. Augustine wanted them in; Jerome said they didn't belong. Jerome's Vulgate became the official "Scripture" of the Catholic Church through the ensuing centuries. The books of the Apocrypha had been in the Septuagint, and they were occasionally quoted by the church fathers (but never by the apostles). All through the Middle Ages, those books are a matter of dispute in the Catholic Church, but they were never officially brought in until 1546 at the Council of Trent.

My professor told us that there are sections of the Bible that were taken out, and in these section there is a verse that describes Jesus striking a kid dead because the kid ran into him. My professor says they are stories of Jesus as a kid.
