Gnosticism is a divers system of spiritual beliefs that incorporated pagan, Greek, and Christian ideals to formulate its own system. Each Gnostic teacher added or changed the Gnostic beliefs to fit their own individualized ideals. The first mentions of some of these Gnostic ideals were developed from the 2nd to 4th century AD. The Church exposed these ideals as unorthodox and unchristian but sadly, even today, we can still see some of the ideals being taught. There are a few primary teachers that developed ideals that are familiar still today: Marcion of Sinope, Valentinus, Theodotus of Byzantium, Arius of Alexandar, Pelagiu, Cerinthus, Menander, Sabellius, Basilides, and Montanus. There are other early Gnostic teachers but their forms of Gnosticism are far more separated from orthodoxy Christianity. These same teachings influence modern religions and movements such as the Word of Faith movement, Jehovah's Witnesses, Mormonism, and Islam.
