GNOSTICISM AND THE LGBTQ+ MOVEMENT

I saw something interesting posted on facebook by a friend of mine. (I won't name him because he is a friend and I want to keep him as such. Also, he is not a Christian so what I'm saying in this post is not directed to him. This post is intended for my fellow Christians to think about.) Many years ago, when I was eleven or twelve years old I heard and believed a heresy from Sunday school teacher. What he taught us, with the help of lots of snazzy charts and diagrams was this: We are spirits That have souls and live in bodies. Of course, any Orthodox or Roman Catholic Christian, and most Protestant Christians, should easily recognize this heresy as Gnosticism. But here is what my friend said, and again, my friend is not a Christian and, to the best of my knowledge, is unfamiliar with the Gnostic heresy; he was merely seeking to explain the sexual ideas that are popular in the larger Western post-Christian society. So this is what he said: a persons identity (whether he thinks of himself as male, female, or other) is located in his mind which, if one is not a materialist, usually means the spirit, while who a person is attracted to (e.g. wants to have sex with) is determined by his heart/soul, and a person's sex is determined by his body. When I saw what my friend said I was astounded. As Ecclesiastes says, there is nothing new under the sun. Of course, I knew before I saw my friend's Facebook post that there was some kind of link to Gnostic anthropology but I hadn't thought it all the way through. Now that my friend explained it I see it clearly. There is nothing that can or should be done to try to convince a non-Christian (they won't believe us) that this idea is an error, but we can and should strive to show Christians that the whole LGBTQ+ movement is merely the most recent iteration of the Gnostic understanding or human personhood. Of course, the Christian understanding of a human person is that we are a spirit and a soul and a body, created by God to be such, in unity without confusion, and forever. But there is a deceiver who does his best to make people think they are not one being, who tries his best to think there is and ought to be confusion between the spirit, soul, and body. It is the demonic idea, the lies the enemey puts into people's minds that must be combatted through prayer and fasting and a liberal application of holy water.
