The name of Jesus and His teachings captured people’s hearts and minds throughout much of the world long before Christianity was legal. Long before armies and governments protected or supported it, and then long after Emperor Constantine’s reign as many leaders misused it for their own gains or religious views. Christianity also survived brutal persecutions during many centuries, including the present. Its growth seems inexplicable. The Pew Research Center’s recent work supports the claim that “Christianity is the only religion in the world with a major presence on every continent.” Inexplicable traces this remarkable spread of Jesus’s followers.
