This article catalogs some of the movements within early Christianity at variance with the orthodox faith. Material from this guide came from History of the Christian Church by Henry C. Sheldon, the Encyclopaedia Britannica, and A History of Heresy by David Christie-Murray.
Ebionism
Ebionites considered Christianity as a sect of Judaism. The believed the Jesus was a mere man of exceptional righteousness and a superior endowment of the Spirit which came upon him at his baptism. Some Ebionites accepted, and some rejected, the supernatural conception of Christ. Ebionites were among the Judaizers who attempted to impose the Law of Moses upon Christians. Ebionites were millenialists–those who believe in a literal 1,000-year reign of Christ on Earth.
The System of Cerinthus
Cerinthus (contemporary of the Apostle John) combined Gnostic views (separating the earthly Jesus who was the son of Joseph and Mary from the heavenly Christ) with the views of the Judaizers. Cerinthus was also a millinealist (also known as chiliasm).
The Pseudo-Clementine System
It is based on a 2nd century document claiming to be a collection of sermons by Clement of Rome. These writings emphasize the unity of God (as opposed to the Trinity), representing God as dwelling in bodily form at the center of the universe. The work is strongly dualist — dividing everything into a thing and its opposite (male-female, good-evil, Christ-antichrist, etc.).
Gnosticism
Predating Christianity, it is not correct to consider Gnosticism as merely a Christian heresy. Gnosticism may be considered a religion on its own. A syncretistic religion (a religion which borrows freely from and integrates elements of other religions), Gnosticism contains elements of Judaism, Jewish speculation, Christianity, Zoroastrianism and other Mediterranean and Eastern mystery religions. While there are many varieties of Gnosticism, they all shared an elitist view that some people are capable of knowing (hence the word Gnostic from the Greek word gnosis = knowledge) and understanding the secrets and those who were unredeemable. Salvation is a matter of knowledge rather than works or faith.
Gnostics had elaborate systems of heavenly beings and their relationships borrowed from Jewish speculation and such works as the Book of Enoch. Gnostics are strong dualists. They held that there is a Supreme Being, unknowable to the world, from whom unfolded attributes and powers who manifested in personal form. There is a chain of these beings, called AEons, linking the Supreme Being to the material world. “The Savior” was one of the AEons who united himself with Jesus of Nazareth in an un-real incarnation. Mankind is divided into immutable classes–some destined for salvation and some for destruction. Gnosticism was strongest in the 2nd century. Continue reading →
