Jesus taught Gnosticism to his selected followers and spoke in parables to the crowds. These 13 codices are referred to as "The Jesus Gospels", "The Gnostic Gospels" or the Nag Hammadi Library and date from the first 2 or 3 centuries of the Christian era.
Nag Hammadi codices. Discovered in a clay jar in Egypt in 1945. The codices were eventually discovered to be secret sacred Christian texts. The books were created over 1,500 years ago, during the first centuries of Christianity. Some of them had never been mentioned before, in any Christian literature; others had been declared heresy, and banned by the Church. They offer a counter-point to accepted ecclesiastical literature, and have been controversial ever since their discovery.
