This, ironically, is the Pope trying to make a point about homosexuality:
People dispute the idea that they have a nature, given to them by their bodily identity, that serves as a defining element of the human being. They deny their nature and decide that it is not something previously given to them, but that they make it for themselves. The manipulation of nature, which we deplore today where our environment is concerned, now becomes man’s fundamental choice where he himself is concerned. When freedom to be creative becomes the freedom to create oneself, then necessarily the Maker himself is denied and ultimately man too is stripped of his dignity as a creature of God.
But I was an adolescent growing up in a conservative Catholic home, and that’s when I was disputing the idea that I have a nature, hoping instead that my sexuality was a fundamental choice I could make. Finally in the 80s I accepted I was gay and stopped stripping myself of dignity by trying to live a lie in discord with my nature.
The Pope thinks he’s arguing against homosexuality, when in fact he’s explaining why ex-gay therapy is a moral shame.
