Heresy: Robb Moser
Genesis to Revelation Bible Blogs
Early church heresy and heretics was doctrine and proponents departing from established orthodox beliefs, primarily focusing on the nature of Jesus Christ and the Trinity during the first few centuries. Key figures included Arius (Arianism), Montanus (Montanism), and Pelagius, often influencing movements like Gnosticism or challenging church structure, largely forcing the development of creeds.
Here are the major early church heresies and heretics:
Major Early Heresies and Movements
Gnosticism (1st-2nd Century): Taught that salvation came through secret knowledge and that the physical world was inherently evil.
Arianism (AD 250–336): Founded by Arius, this heresy denied the full divinity of Jesus Christ, asserting He was created by the Father.
Montanism (173 AD): Founded by Montanus, it emphasized new prophetic revelations and strict asceticism, often claiming the church lacked power to forgive certain sins.
Docetism (2nd Century): Proposed that Jesus only appeared to have a human body and was not truly physical.
Marcionism (2nd Century): Taught that the God of the Old Testament was different from the God of the New Testament.
Pelagianism (4th Century): Denied original sin and argued that humans could earn salvation through their own efforts.
Donatism (4th Century): Argued that the validity of sacraments depended on the moral purity of the minister.
Key Heretical Figures
Simon Magus (1st Century): Cited as the first major heretic, known for trying to buy spiritual power.
Arius (250–336): Alexandrian priest whose teachings prompted the First Council of Nicaea.
Montanus (2nd Century): Prophesied in Asia Minor, starting the Montanist movement.
Mani (250 AD): Founder of Manichaeism, which viewed the world as a battle between good (light) and evil (darkness).
Nestorius (5th Century): Taught that Christ was two distinct persons (divine and human) rather than one person with two natures.
These heresies, such as Arianism and Gnosticism, were countered through ecumenical councils, which defined orthodox doctrine, such as the Nicene Creed.
