Until the time comes that you can show me in the doctrine of the Catholic Church where abortion is allowed, homosexual “marriage” is allowed, and women preachers are allowed your copying and pasting means nothing. Laymen are sinners. Or are you aware of that? There are more devout Catholics that practice their faith than the largest protestant denomination in the United States. I suggest you start worrying about the protestant churches all over the country that should be ashamed to call themselves houses of worship.
If these are the only "doctrines" you are going by to determine which "house of worship" is right, then you will have to concede Islam is right - they don't allow abortion, homosexual marriage and certainly not women preachers. You're going to have to use a bit finer criteria if your claim holds any weight.
What I have experienced is the more closely a denomination holds to the Biblical truth of the Gospel of the grace of God through faith in Jesus Christ the more conservative they are in "social" issues and the more consistent and unified their congregation is.
