The Lost Gospels: According to some estimates, early Christians wrote at least twenty gospels that werent included in the bible. Many of these non-biblical gospels apparently disappeared later, although its possible that copies of some of them still survive at unknown locations. Luckily, several that appeared to be missing have been found again in modern times. But some are still missing, and could be permanently lost.Gospels that were left out of the Bible are called non-canonical gospels. Many scholars also call them apocryphal gospels, because most of them have unknown origins. This uncertainty about their origins was one reason many of them were excluded from the Bible. But some were also excluded because they expressed unorthodox or heretical views.
