The only way to move forward successfully is by learning from the past.
How can we Christians move forward, when our very existence seems imperiled? We already know the way, for we've been through this before. But we have forgotten; we have cryptomnesia.
Cryptomnesia is the reappearance of a suppressed or forgotten memory which is mistaken for a new experience. The world is changing, and it is changing fast. Social media friendships, global commerce, online education, populist uprisings, e-books, and smartphones are just a sample of the Internet's growing impact on our lives. Americans are rapidly becoming more mobile, worldly, and secular - all while it feels like the church we know is being left behind. Growing numbers of "spiritual but not religious" show disinterest in church, and mainline churches fear imminent demise.
How do we find a way forward? Ironically, by looking backward. We are not the first to experience globalization. In fact, the early church emerged in an age of globalization - the product of the Greco-Roman Empire and its mammoth road-building efforts on three continents. People were connected in ways they had never experienced: Roman citizens were bombarded with new cultures, new commerce, new foods, new ideas, new philosophies, new religions. It was an era of massive dislocation, and at the same time, exactly the right environment for Christianity to emerge and thrive.
