The germ of monophysitism may be found in the logos-sarx (Word-flesh) theology of the Alexandrian church. The question of how Christ's personality should be acknowledged could not be avoided, however, once the Creed of Nicaea (325) confessed that he was "of one substance with the Father". If this was so, how was Christ to be considered of one substance with man? Fifty years later, the answer was given uncompromisingly by Apollinaris, bishop of Laodicea in Syria, a friend of Athanaisius and an Alexandrian-trained theologian. Scripture, he maintained, emphasised that Christ was "one". In De fide et incarnatione he wrote, "There is no distinction in Holy Scripture between the Word and His flesh; He is one energy, one persom. one Hypostasis [individuality], at once wholly God and wholly man." This exactly summed up what was to become the Monophysite position: Christ was "out of two natures," one.

p. 115:
The Relationship between God and Humankind
In the past, the question of whether Muslims and Christians worship the same God was not uncommonly given a negative answer - in other words, "Allah" was taken to be a conceptual idol.
Parshall("The Cross and the Crescent", p.24)...comments "Islam presents an inadequate and incomplete - but not totally misguided - view of God"
Chapman("Rethinking the Gospel of Muslims", p.122; here Chapman is explicitly citing an oft-expressed idea of Cragg's)...points out that both Muslims and Christians can assent to a series of simple propositions: "God creates. God is one. God rules. God reveals. God loves. God judges. God forgives." While there is no dispute between Muslims and Christians as to WHETHER God does these things, however, there is a difference concerning HOW he accomplishes them.
