For the first 4 centuries of the 1st Millennium, Christianity was practiced openly, for the most part. When the Goths, Visigoths and the Huns invaded the Roman Empire, Christianity went underground. Monasteries were established in very remote places to preserve Christianity. And they stayed there until the end of the dark ages and the beginning of the Reformation. The single act that started the Reformation was Johannes Gutenberg printing the bible. It wasn’t like todays portable bible. It was as big as a desk. But it was printed in the language of the people. So, everyone could read the bible. And when they heard it read, it changed the world. Just like it did in the 1st century. The bible has become the bestselling book in history. Today in America, most every home has at least 1 bible. Most homes have 4 or 5 bibles. But just like in the 4th century, there is a darkness coming upon the world. It is creeping in and is insidious. So, what is the Christian world going to do? Are they going to hide in monasteries? Christianity was not meant to be practiced inside a church building. Just like the church in the 1st century, they took it to the world. And guess what? The world changed. And yes, the Christians were persecuted and killed. But what happened is that gospel was preached to the world. Remember, Jesus said that He was not returning until the gospel was preached to the whole world. So, are you going to hide your light until it goes out?
