Monophysitism ( or ;
Greek: μονοφυσιτισμός from μόνος
monos, "only, single" and φύσις
physis, "nature"), is the
Christological position that, after the union of the divine and the human in the historical Incarnation,
Jesus Christ, as the incarnation of the eternal Son or Word (
Logos) of God, had only a single "nature" which was either divine or a synthesis of divine and human. Monophysitism is contrasted to
dyophysitism (or dia-, dio-, or duophysitism) which maintains that Christ maintained two natures, one divine and one human, after the Incarnation.
