Monophysitism is a term that refers to a controversial theological belief that Jesus Christ had only one nature instead of the commonly accepted two natures. Some synonyms for Monophysitism include Eutychianism, miaphysitism, and the Cyrillian viewpoint. Eutychianism is a belief that Christ's divine nature had entirely absorbed his human nature, while miaphysitism emphasizes both the divine and human natures of Christ as being united into a single person. The Cyrillian viewpoint asserts that Christ's two natures were united without being confused or changed. These different synonyms highlight the complexity and diversity of the theological debates regarding Christ's nature in the early Christian church.
