OK. Just that in the case of the Gnostic Gospel of Thomas, that was NOT what was meant.
""The Gospel of Thomas declares that a woman cannot be saved unless God first changes her into a man (the very last verse of Thomas, 114)."
When a woman (or a man, for mankind is the feminine aspect or spirit) is saved, that is when the transformation starts and the feminine prepares to becomes one with the masculine. That's what the marriage is. A twaining of your mind and the mind of Christ and we become bone of his bone and flesh of his flesh, in a spiritual sense. Your will is sublimated to the will of God, as Christ sublimated his will to the will of the Father when he said, 'Not my will, but thine be done.'
Now, in that He is now the eternal mediator between man and God, it is for us as individuals to sublimated our will to the will of Christ, (our husband, if you will) who is the express image of the Father within us, for Christ dwells within us and we in Him. Ideally, in conscious internal dialogue.
So I see no problem with the Thomas statement, though I wouldn't take it to mean a natural happening, for what profit has the flesh? The statement could serve as a metaphor for the wedding between Christ and His church, a confirmation of the inner process of re-uniting with God and realizing our salvation on an individual basis.
