The Death of Christianity in the West

The West is definitively post-Christian with the sole exception of some places in America. In Europe, if you look at the latest polls for most Western European countries, even the stats in Italy for regular church attendance shocked me. A quarter of UK millennials didn't even know who the baby in the manger was. Most of them have no idea what the Trinity means. Even basic, ascetical differences between Protestants and Catholics are misunderstood. And this is not something that we can sustain over the long haul.
