Biblically speaking, a church member who is in sin, should be confronted. If that individual refuses to repent, he/she is to be put out of the church.
So, if homosexuals were always there, were open about it so people knew, were members of the church and no one confronted them about it, then the church leadership as a whole sinned.
I'm not an expert on the Bible, but I would be interested if you could point out where it says this in the New Testament. I know there is a lot of stuff in there about checking out the beam in your own eye first, etc.
I wonder how this would apply to those churches attended by members of the Mafia.

I don't think that gay people used to be so open about their inclination. It just didn't take a rocket scientist for people who knew them to figure it out. I actually have no idea how the people I discussed acted on their particular inclination. If some people knew they were probably gay, but knew nothing about their particular relationships, what do you think should have been done?
It's obvious that gay people didn't just enter the church, in particular the Catholic Church, in recent times.
