We do have some works in which by some are considered part of biblical literature whilst others consider them as works outside an accepted canon of scripture. Those many writings form a body of esoteric writings that were at first prized, later tolerated, and finally excluded. In its broadest sense apocrypha has come to mean any writings of dubious authority.
For millennia, it was thought that the Christian apocrypha were rejected, suppressed and destroyed by leaders of the early church. But today, scholars of the Christian apocrypha are challenging this view, claiming that the apocrypha were composed and transmitted throughout Christian history – and that they were valued not only by “heretics,” but also by writers within the church who did not hesitate to promote and even create apocryphal texts to serve their own interests.
