Divine necessity and created contingence in Aquinas

It is becoming increasingly more common in Christian theism to conclude that the classical predication of a necessary God who interacts with contingent creation is logical inconsistency. This criticism is especially made by Process theists, but joining with them have been proponents of Open theism as well as others who seek to more closely unite God with the contingency in creation. It is feared that a God who is the transcendent cause of all that exists is unable to relate to creation without necessarily determining it. Yet Thomas Aquinas was not unaware of the potential difficulty in maintaining both a necessary God and created contingency and postulated a solution to the dialectic that fits comfortably within the classical synthesis. This paper examines Aquinas' solution against the charge of incoherence and finds that far from being inconsistent, it coherently succeeds in reconciling the dialectic.
