Is there any chance that you (monophysite Orthodox Coptic Church) will become united (unified) with other Orthodox Churches worldwide?
The term monophysite comes from two Greek words meaning "single nature". Monophysitism endorses the merging of the Lord Jesus Christ's Humanity into His Divinity. So that effectively meant that in the Lord Jesus Christ there was only a single nature, a Divine Nature. This is NOT what the Coptic Orthodox believes. We believe that "the Lord Jesus Christ was a perfect human and a perfect Divinity and His two natures are united together into a one nature (Miaphysitism). Also we believe that His Divinity parted not from His Humanity not even for a single moment nor a twinkling of an eye" and we recite this statement in every Divine Liturgy. The term (miaphysite) is used by St. Cyril and it reflects the belief of the Coptic Church in the One Nature of the Lord Jesus Christ. Unfortunately until today, the Coptic Church has been accused of believing in monophysitism (single nature) which is a heresy condemned by the Coptic Church. The Eastern Orthodox and Oriental Orthodox (Miaphysite) Churches now have come to a realization that they profess the same faith. Their separation in the fifth and sixth centuries can now be seen as having been due to linguistic, political and national factors. Since they have all along had the same faith, all that remains for the two churches now to do is to remove a few secondary difficulties such as mutual anathemas, the non-recognition of each other's saints and parallel jurisdictions. When these difficulties are resolved, a new step will be achieved in the Ecumenical Movement, which eagerly desires the union of all churches.
