Reason is Ministerial

...reason always functions as a servant, never as a master, to theology. Its proper place with respect to theology is to provide whatever tools might be helpful for theology to carry out its own task.4 It also means that the law of contradiction, and the use of that law, can never finally determine whether or not a particular Christian doctrine is true. That determination is left to revelation. What reason can do is help theology to organize, articulate, and expand its truths in such a way as to clarify their meaning.
