The first schism in the Church occurred in the middle of the fifth century, in 451 AD, due to the different teachings on the Nature of Christ. Another schism occurred in the 11th century between the Roman Catholics and the Byzantine Orthodox due to the different teachings on the procession of the Holy Spirit. A third major schism occurred in the 15th century caused by Luther, the establisher of Protestantism. Different dogmas sprang up afterwards within Protestantism.
