Rejection of simplistic Nestorianism label
The church tends to reject the idea that its faith can be reduced to the term Nestorian.
What it is: The Assyrian Church of the East usually rejects that its doctrine be simply identified as 'Nestorian' in classic polemical sense.
How the tradition understands it: The church's self-understanding emphasizes fidelity to the one Christ, without accepting caricatures that accuse it of dividing Christ into two persons.
Basis and context: The label arose in ancient controversies and was repeated for centuries in Western and Byzantine literature.
Debates and variations: Contemporary historiography has shown greater complexity in the relation between the church, Nestorius, and ancient Christological terminology.
