The existential and ontological meaning of man's created existence is precisely that God did not have to create, that it was a free act of Divine freedom. But— and here is the great difficulty created by an unbalanced Christianity on the doctrine of grace and freedom— in freely creating man God willed to give man an inner spiritual freedom. In no sense is this a Pelagian or Semi-Pelagian position. The balanced synergistic doctrine of the early and Eastern Church, a doctrine misunderstood and undermined by Latin Christianity in general from Saint Augustine on— although there was always opposition to this in the Latin Church— always understood that God initiates, accompanies, and completes everything in the process of salvation. What it always rejected— both spontaneously and intellectually— is the idea of irresistible grace, the idea that man has no participating role in his salvation.

Augustine's writings found their way to parts of the West Roman provinces. Saint John Cassian (circa 360-433), former ascetic in the deserts of Egypt and then deacon of the Patriarch of Constantinople Saint John Chrysostom, challenged Augustine's teaching about original sin and pre-destination without mentioning him. The teachings of Augustine on these points were condemned by the Council of Orange in 529.[ 18 ] Augustine's writings completely captured the 8th century Carolingian tradition which knew basically only Augustine until the 12th century. At that time the Franks acquired a translation of Saint John of Damascus' "Book on the Orthodox Faith" which they simply understood within their own Augustinian categories. By the 11th century the Franks had taken over all of Western Europe, except Spain, by either conquest or diplomacy. The Spanish Romans under Arab rule were still under the direct surveillance of the Roman Emperor of Constantinople New Rome. The Umayad Arabs of Spain and the Abbasid Arabs of Damascus and then Baghdad called their Roman Orthodox subjects Melkites, i.e. those who belong to the religion of the Roman Emperor in New Rome Constantinople.
