Nestorianism is a term used in Christian theology and Church history to refer to several mutually related but doctrinally distinct sets of teachings that fall under the umbrella term Dyophysitism, such as two natures in Christ or two persons in Christ. The extent to which those two definitions are actually distinct is also debatable. The first meaning of the term is related to the teachings of Christian theologian Nestorius as according to his immediate opponents at the Council of Ephesus and traditionally used by Miaphysites. The second meaning of the term relates to a set of later theological teachings that were traditionally labeled as Nestorian by Chalcedonians but differ in the teachings of Nestorius in origin, scope and terminology. Per the latter definition, the Oxford English Dictionary defines Nestorianism as:"The doctrine of Nestorius, Patriarch of Constantinople, by which Christ is asserted to have had distinct human and divine persons."
