At this moment, about one-third of the world’s population makes some sort of claim to be a follower of Christ.  That means that the group Jesus launched with just a few, has spread and grown more dynamically than any other movement in history. How did this happen? In Episode 18 of One Hundred Plus, Mike is going to leverage the impact of Saint Columba, a 6th century Irish missionary, to provide an overview of the history of mission.  He will back up to show Jesus commissioning his simple and unimpressive followers to launch the church, and then trace how it grows to become, what is now, the oldest, largest, longest-lasting, most geographically-dispersed and ethnically-diverse organization in history.
