Christians in Europe? I think a convention of every Christian in Western and Central Europe could be held in a phone booth.
Believing Christians are bailing out of Europe. I just finished a telephone call with a Dutch woman I know who lives in Groningen. A devout Christian, she is trying to get all the paperwork together so that she and her husband can emigrate to the US or Canada.
You might be surprised. I've handfulls of Christian friends in Romania, Poland, Ireland, and the Czech Republic. Same can be said for Italy.Granted, yes, they are mostly in pockets.
I question whether Western Europe has the societal stability and commonaltiy to survive the onslaught, particularly Northern Europe. All but Ireland seem very much devoid of fight, faith, or spirit.
