As a former Catholic, I was taught and trained that there could be no divorce, period (I'm 68 years old) and homosexuality was always a most grievous sin
If it's changed ... shame on the Catholics for allowing that indoctrination to enter in your consciosness
And a homosexual act IS always a most grievous sin.
That's what it says in the Bible, that's what it says in the Catechism, that's what Pope Francis says. None of that has changed.
If somebody told you that changed, they lied to you.
