While the text is said to not be very credible, and is missing over half of the initial text, I think the text we do have is very interesting.
Mary being a teacher to the apostles here is fascinating to me, she is essentially preaching to them, something that is often argued about amongst different denominations. The actual premise of her, as a woman, discussing theology is very controversial for the time period. Even the Apostles say this, Peter and Andrew directly claiming that they believe she must be lying, and that these concepts are hard to believe coming from her.
Another thing I found interesting was when Jesus said, “How wonderful you are for not wavering when seeing me!” He’s almost refreshed at the idea that Mary so clearly has told him she saw him, happy that she doesn’t waver at his presence and is completely accepting of his words and willing to follow them and think further on them so that she may understand when she does not. This is contrasted with the deciples, who are distressed earlier when he gives them knews that they cannot comprehend, and need Mary to encourage them so that they might think more about what his words meant.
Furthermore, I wonder why the text was hidden in the first place, if it is not credible like people claim, then what reason would there be for it to be hidden away? I’m not going to speculate more though, because I’m sure I could find the speculation of people more knowledgeable on the topics of religion and lost literature than me and it would probably be more accurate or detailed than anything I could come up with.
