Miaphysitism (sometimes called henophysitism) is a Christological formula of the Oriental Orthodox Churches and of the various churches adhering to the first three Ecumenical Councils.
Miaphysitism holds that in the one person of Jesus Christ, Divinity and Humanity are united in one or single nature ("physis"), the two being united without separation, without confusion, and without alteration.
Historically, Chalcedonian Christians have considered Miaphysitism in general to be amenable to an orthodox interpretation, but they have nevertheless perceived the Miaphysitism of the non-Chalcedonians to be a form of Monophysitism.
The Oriental Orthodox Churches themselves reject this characterization.
