Eutychianism
In one sentence
An extreme Christological view associated with the mixing or absorption of Christ’s humanity into divinity.
In simple terms
Eutychianism is associated with the idea that after the union Christ’s humanity is absorbed or altered by the divine nature.
Biblical truth
Scripture continues to speak of Christ’s real humanity after the incarnation: he has a body, human willing, suffers, and rises.
Key Scriptures
Luke 24:39 · Matt. 26:39 · John 20:27 · Heb. 2:14–18 · 1 Tim. 2:5
Example
If humanity ceases to be fully human after the incarnation, Christ is no longer “like us” in the full sense.
Who holds it
Historically associated with the monk Eutyches and mid-fifth-century controversies; the precision of some later descriptions is debated.
Opposing view
Chalcedonian Christology
Not to be confused with
Do not automatically equate it with the Miaphysitism of the Oriental Orthodox churches.
History
The rejection of extreme mixing of the natures formed part of the context of the Council of Chalcedon in 451.
Main point of debate
The main question is whether divine and human remain genuinely distinguishable and complete after their union in the one Christ.
