Fr. Barron has recently observed:
In justifying the transformation that he has undergone, Jenner consistently says something along these lines: “Deep down, I always knew that I was a woman, but I felt trapped in the body of a man. Therefore, I have the right to change my body to bring it in line with my true identity.” Notice how the mind or the will—the inner self—is casually identified as the “real me” whereas the body is presented as an antagonist which can and should be manipulated by the authentic self. The soul and the body are in a master/slave relationship, the former legitimately dominating and re-making the latter. This schema is, to a tee, gnostic—and just as repugnant to Biblical religion as it was nineteen hundred years ago. For Biblical people, the body can never be construed as a prison for the soul, nor as an object for the soul’s manipulation. Moreover, the mind or will is not the “true self” standing over and against the body; rather, the body, with its distinctive form, intelligibility, and finality, is an essential constituent of the true self. Until we realize that the lionization of Caitlyn Jenner amounts to an embracing of Gnosticism, we haven’t grasped the nettle of the issue.
Ah, the age-old heresy of Gnosticism, the doctrine of salvation by knowledge, derived from the etymology of gnosis, "knowledge." While the Church teaches that the soul attains its salvation by obedience of mind and will to God, by grace through faith working in love, Gnosticism places the soul’s salvation solely in one’s possession of a quasi-intuitive knowledge of the mysteries of the universe, and of magic formulae indicative of that knowledge. It is prevalent in dissident feminist ideology as well as creation spirituality’s influence on “Catholic feminism,” in which the subjective “goddess within” takes the place of “I AM who AM” and is worshipped as such.
