One problem I see with your view is that there are many practicing Catholics who use birth control yet attend Catholic mass and belong to the church. They say their Act of Contrition every night and promise to amend their life and never do.
Though it is true that many homosexuals have no intention of ceasing their perversion that shouldnt prevent them from joining a Church. There are many people who steal and attend mass on Sunday .Even some in the Mafia go to church. Church is not for the saints among us but the sinners. Most go to Church because they are comforted by what they perceive is a closeness to God in that Church, personally I dont need a Church to be comforted,My God is everywhere, but I wouldnt deny it to those who do.
Absolutely correct on that one.
I myself am a habitual, repeat offender. But I deplore it. I repent it. And with God's help through His Church, I am struggling towards living a Christian life.
But the church cannot help sinners who do not repent. Accepting a member who says, "I don't regret my sins and I have no intention of turning away from them," would be the same as saying, "We don't care about your soul, all we want is your dues."
And THAT would be religious hypocrisy at its worst.
