Paul says that prior to his conversion he persecuted early Christians "beyond measure", more specifically Hellenised diaspora Jewish members who had returned to the area of Jerusalem. According to James Dunn, the Jerusalem community consisted of "Hebrews," Jews speaking both Aramaic and Greek, and "Hellenists," Jews speaking only Greek, possibly diaspora Jews who had resettled in Jerusalem. Paul's initial persecution of Christians probably was directed against these Greek-speaking "Hellenists" due to their anti-Temple attitude. Within the early Jewish Christian community, this also set them apart from the "Hebrews" and their continuing participation in the Temple cult.
