This is from a guy that I have researched and studied behind. His website is
http://www.scriptual-truth.com. You should check out his edited version of the Gospel of Thomas, and there are many other great reads on his site. It might make more sense to you guys. We tend to look at and read things from a physical perspective and we miss the spiritual aspect of God's teachings that have been left to us, like this Gospel, the Book of Enoch, the Book of Adam and Eve, the Book of Jasher, and many others.
Here is another way to look at the last verse.
114) Simon Peter (The Church) said to him, let Mary (Out of whom the 7 demons of the age of flesh were cast) leave us, for women (Those who through the flesh deliver us into the world of the flesh) are (Or, by this analogy anyway, would seem to be) not worthy of life. (The Church cannot imagine Jesus transforming the lower, physical, or female into the upper, or spiritual, or male.) Jesus said, I myself shall lead her (That is, the world itself unfolds as Jesus would have it) in order to make her male, (Cause that which brings forth beings of flesh to cease, and to instead bring forth spiritual beings) so that she too may become a living spirit resembling you males (Living spirits). For every woman (Fleshly person—for even we men are called the bride of Christ) who will make herself male (Spiritual) will enter the Kingdom of heaven. (Because he makes us like himself.)
