The Coptic Church regards itself as having never believed in [[monophysitism]] the way it was portrayed in the Council of Chalcedon, but rather as having always believed in [[miaphysitism]] (a doctrine that [[Oriental Orthodox]] Churches regard as correct and orthodox doctrine). In that council, monophysitism meant believing in one nature of Jesus Christ. Copts believe that the Lord is perfect in his divinity, and he is perfect in his humanity, but his divinity and His humanity were united in one nature called "the nature of the incarnate Word," which was articulated by St. [[Cyril of Alexandria]]. Copts thus believe in two natures "human" and "divine" that are united in one "without mingling, without confusion, and without alteration" (from the declaration of faith at the end of the Coptic divine liturgy). These two natures "did not separate for a moment or the twinkling of an eye" (also from the declaration of faith at the end of the Coptic divine liturgy).
