Monophysitism definitions

(Christianity) A Christian belief which holds that the human nature of Jesus Christ was essentially absorbed by the divine, and thus that he essentially had but one nature, contrary to the orthodox view that Christ has two natures, both fully human and fully divine. A variant is apollonarianism, which has gnostic overtones and used hellenistic ideas alien to orthodox Christianity.

Origin of monophysitism

Greek μονοφυσιτισμός, from μόνος (only one) + φύσις (nature), 'belief to a single nature'
