Now, argues Dreher, it could be time for Christians to ensure history repeats itself. "There are a number of lessons, but they all depend on a conviction that believers have to understand themselves as exiles and change their lives to live accordingly. That means separating in limited, targeted ways from the secularizing mainstream, and embracing truly countercultural discipleship," her writes.
"This can include changes as big as withdrawing from public schools (or Christian-in-name-only religious schools), or as seemingly small as refusing to let our kids be a part of immersive smartphone culture."
This still sounds a bit isolationist, doesn't it? "Does this mean running to the bunker with a Bible in hand, and watching the world go to hell with our fellow pious preppers? Not at all," argues Dreher. "But if we are to remain faithful under increasingly adverse cultural conditions and bear authentic witness to post-Christian America, we are going to have to spend a lot more time within our Christian community in rigorous spiritual training."
Now is not a time to compromise on the central tenets of our faith, argues Dreher. "Christians can best serve the common good by serving God first, and coming to the public square as Christians in full, not as conformists or compromisers," he writes.
"If we are refused admission because our faith offends, so let it be. It is far more important to be a faithful Christian than to be a good American. Time was that there was no conflict between the two goals. Those days are over."
"No matter which tradition you worship in, the future of Christianity in America will be a lot more Benedictine in spirit and practice - or it won't be at all."
