Maybe 10 or 20 years ago all sorts of people were proclaiming these liberal, progressive Churches to be the future. Even recently, an atheist friend of mine was still under this delusion. Of course, its telling that he was an atheist telling me this, and not an Episcopalian or liberal Christian. Many Churches are declining right now, but the liberal ones are declining much faster. There’s not a single liberal denomination (to my knowledge) that is doing well.
And, why go to Church if you can just sleep in? Why try to be a Christian, if you’re basically guaranteed salvation no matter what you do? They don’t teach about sin, and by extension, they can’t preach about being Holy and serving God, if you throw sin out of the equation.
Anyways, I’m glad some denominations did adopt all the liberal teachings: gay marriage, abortion, God is a woman, or now maybe God is homosexual. Women priests, etc. By your fruits you shall know them. And, I think by any analysis, they have turned into a dead branch that bears no fruit. Eventually they will whither and die.
Lastly, yes, there are small but vibrant Catholic communities in most of the Nordic countries. Thank God. In fact, in Iceland the Catholic Church is the second largest religious group. That’s not the case in Sweden, yet. But hopefully, will be.
