The Coptic Church believes in one nature of God .
The Coptic Orthodox Church professes that the union of the Word of God with the flesh is as the union of the soul with the body , and as the union of fire with iron , which although they are of different natures , yet , by their union , become one .
This nature is neither merely the Godhead , nor the Manhood alone . It is the one nature , which has the properties of the two natures with neither mixture , nor confusion or alteration .
Jesus is perfect in His Godhead and perfect in His Manhood . For the Copts ,
Jesus
is God Incarnate .
