The original text of Mary Magdala was said to have been found in a literal hole in the wall, then sold in an antique shop in Cairo. This version was written in Coptic around the 5th century, however, it is currently missing 10 pages out of 19. Just over half the text is lost. Two other partial texts have been found, both written in Greek in the 3rd century. Unfortunately, they do not shed light on the missing parts.
The gospel describes how the disciples are confused about a teaching that Jesus has just told them. Mary tries to comfort them by telling them of knowledge that Jesus has told her, however, they accuse her of making it up. They jeer at her until she cries and then go off to preach their not-quite-on-message message to the masses.
The contents have been questioned, due to them being written well after the living memory of Jesus. However, some of the texts were still written before the compilation of the Bible in the 4th century. This means that this gospel could have been in the Bible, but wasn’t.
There are a few reasons why this gospel might have been lost to time. One is that Mary Magdala is said to have been a prostitute. But nowhere in the Bible says this. That is because it was made up by one of the catholic popes, who combined three different women mentioned under one name.
Another argument to be made is that Mary was possessed by seven sins. However, that was added on to the text later, based off of a story from Luke.
Time and time again, Mary is brushed off and away from the story. Maybe because of patriarchal thinking, that no woman should have ever been closest to the Savior than any of his apostles. Perhaps people just perpetuated the story that they had been taught. Or perhaps, a refusal to see her in a different light.
