The New Testament Apocrypha
The New Testament Apocrypha was deemed to be heretical in nature as it happened at one point in time. They were believed to have religious ideas and points of view that contradicted what was in the agreed consensus. And for those who chose to stand by such nonconformist beliefs had been labeled as a heretic for several centuries.
Athanasius The Great
Remarkably, there was an understandable reason why the texts of the New Testament Apocrypha were believed to be heretical. There was a man known as Athanasius the Great, who served as the twentieth bishop of Alexandria in the fourth century A.D., who did not think of them as official doctrines.
