Medieval political philosophy in Europe was heavily influenced by Christian thinking. It had much in common with the Mutazalite Islamic thinking in that the Roman Catholics though subordinating philosophy to theology did not subject reason to revelation but in the case of contradictions, subordinated reason to faith as the Asharite of Islam. The Scholastics by combining the philosophy of Aristotle with the Christianity of St. Augustine emphasized the potential harmony inherent in reason and revelation. Perhaps the most influential political philosopher of medieval Europe was St. Thomas Aquinas who helped reintroduce Aristotle's works, which had only been transmitted to Catholic Europe through Muslim Spain, along with the commentaries of Averroes. Aquinas's use of them set the agenda, for scholastic political philosophy dominated European thought for centuries even unto the Renaissance.
