<sod>  The '''Confession of Chalcedon''' (also '''Definition''' or '''Creed of Chalcedon'''), also known as the "Doctrine of the Hypostatic Union" or the "Two-Nature Doctrine", was adopted at the [[Council of Chalcedon]] in [[451]] in [[Asia Minor]]. That Council of Chalcedon is one of the seven [[ecumenical council]]s accepted by Eastern Orthodox, Catholic, and many Protestant Christian churches.  It is the first Council ''not'' recognized by any of the [[Oriental Orthodoxy|Oriental Orthodox]] churches.
 
 ===Oriental Orthodox dissent===
The Chalcedonian creed was written amid controversy between the western and eastern churches over the meaning of the [[Incarnation (Christianity)|Incarnation]] (see [[Christology]]), the ecclesiastical influence of the [[Byzantine emperor|emperor]], and the supremacy of the [[Bishop of Rome]]. The western churches readily accepted the creed, but some eastern churches did not.
 
 The creed became standard orthodox doctrine, while the [[Coptic church of Alexandria]] dissented, holding to [[Cyril of Alexandria|Cyril]]'s formula of the oneness of Christ’s nature as the incarnation of God the Word. This church felt that this understanding required that the creed should have stated that Christ be acknowledged "'''from''' two natures" rather than "'''in''' two natures".
