Here is a concise theological summary of the three early Christological heresies you mentioned. These arose in the early centuries of the church as the church tried to articulate the biblical doctrine of Christ’s nature.
1. Arianism
Founder: Arius (4th century, Alexandria)
Core Claim:
Jesus Christ is not fully God but a created being.
Key Ideas
The Son was created by the Father before the world began.
“There was a time when the Son was not.”
Jesus is the highest creature, but not equal with God the Father.
Why the Church rejected it
It denies the full divinity of Christ.
If Christ is not truly God, He cannot fully save humanity.
Church Response
Condemned at the Council of Nicaea (325 AD).
The Nicene Creed affirmed that the Son is “begotten, not made, of one substance (homoousios) with the Father.”
2. Docetism
Origin: Early Gnostic movements (1st–2nd centuries)
Core Claim:
Jesus only appeared to have a physical body but was not truly human.
Key Ideas
Christ’s body was an illusion or phantom.
God could not take on real flesh, because matter was considered evil.
Therefore Jesus did not truly suffer or die.
Why the Church rejected it
It denies the true humanity of Christ.
The Bible affirms Jesus came in the flesh (1 John 4:2–3).
Theological Importance
Salvation requires Christ to be truly human in order to redeem humanity.
3. Nestorianism
Associated with: Nestorius (5th century, Patriarch of Constantinople)
Core Claim:
Christ consists of two separate persons rather than one person with two natures.
Key Ideas
The divine Logos and the human Jesus were loosely joined.
Rejected calling Mary Theotokos (“Mother of God”).
Preferred Christotokos (“Mother of Christ”).
Why the Church rejected it
It divides Christ into two persons, undermining the unity of Christ.
Orthodox teaching: one person, two natures (divine and human).
Church Response
Condemned at the Council of Ephesus (431 AD).
Quick Comparison
| Heresy | Error About Christ |
|---|---|
| Arianism | Jesus is not fully God |
| Docetism | Jesus is not truly human |
| Nestorianism | Jesus is two persons instead of one |
Orthodox Christian Doctrine:
Christ is one person with two natures — fully God and fully man (defined clearly at the Council of Chalcedon, 451 AD).
