The Iglesia ni Cristo (Tagalog, "Church of Christ") claims to be the true Church established by Christ. Felix Manalo, its founder, proclaimed himself God’s prophet. Many tiny sects today claim to be the true Church, and many individuals claim to be God’s prophet. What makes Iglesia ni Cristo different is that it is not as tiny as others.
One of the most tragic divisions within Christianity is the one between the Catholic Church and the Orthodox churches. Both have valid holy orders and apostolic succession through the episcopacy, both celebrate the same sacraments, both believe almost exactly the same theology, and both proclaim the same faith in Christ. So, why the division? What caused the division?
"Ah, sister, thou hast got the start of us, but we will follow thee as quickly as we may."
