"In the type of the Paraclete, Paul became the Apostle of the Resurrection. Immediately after the Lord's Passion he also was sent to preach". (Theodotus) Paul was originally Saul of Tarsus, who persecuted Gnostics. He is thought to have been present during the execution of Stephan the first Martyr. http://www.studylight.org/enc/cbc/view.cgi?number=T57
