"It is clear that by entering into this union with faith as bridegroom, reason must be subordinate to faith and must be submissive to it. This subjection of the bride to the bridegroom is the necessary consequence of the union, the natural correlative of the bridegroom's descent to the bride and of the bride's elevation to union with the bridegroom. Reason must be submissive to faith especially in their common activity in the theological sphere, by dedicating its entire effort to the service of faith, and by receiving from faith the law of its behavior. Even in its own proper actions and omissions, reason may not proceed as if it stood alone. It may utter no opinion that opposes the law of its bridegroom, and as a true bride must endeavor even in its own affairs to follow the path pointed out by faith's superior wisdom. Reason may no longer regard itself as isolated, because it is no longer isolated. Much less may it look upon the curtailment of the liberty it possesses in the abstract as a misfortune, for the enjoyment of true liberty is not thereby impeded, but is safeguarded and enhanced."
-Matthias Scheeben in The Mysteries of Christianity.
