Introduction

At the beginning of Christianity, the disciple Paul was credited with saving and transforming what was then a small sect into an ever-expanding religion. While St. Paul’s personal and poignant story of conversion could have inspired a growing following, it was ultimately the apostle’s extensive network connections that allowed him to reach people in different parts of the world, ensuring a quick and effective diffusion of his message (Laszlo-Barabasi 2003).
