“Since most gay people experience their homosexual orientation as a part of creation”
What kind of nonsensical tripe is that? The delusions of disordered minds do not define reality.
“if they accept this Church teaching”
What Church teaching? That God makes some people homosexual? AFAIK, that is no part of any Christian theology.
“they must see God as sadistically creating them with an intrinsic orientation to evil.”
Satan is responsible for sodomy and same-sex attraction disorder. Why “must” they blame God for human cooperation with Satanic evil?
Jesuits once were considered the scholars of the Church. Well this Jesuit skipped more than a few chapters.
God doesnt make crap but he does make test.
God test all of us in different ways. If we survive the test we are stronger for it and can grow closer to God.
Homosexuality is a test as is all temptation to sexual sin. You either overcome the temptation and pass the test or you yield to the temptation and fail. The price of failure is high; damnation.
