It is an interesting phenomenon of religious history that the heresy of Luther, taking its rise in a proud rebellion against the teaching authority of the Catholic Church, issued in a pessimistic theology which, exaggerating the effects of original sin, presented human nature as intrinsically corrupt. The human will, bereft of freedom, was radically incapable of pursuing the good, the human reason was powerless to know the truth. As man’s broken will must submit passively to the grace of God, so must his mind now, darkened by sin, allow itself to be led by an occult and irresistible force, a blind and unreasoning faith. The agnosticism of Kant and his disciples, which, denying the validity of metaphysical argument, takes refuge, in order to justify religious belief, either in the dictates of the practical reason or in an unreasoning religious sense, is essentially a Protestant philosophy; and of this tendency to rely upon a blind instinct in religious matters the modern forms of exaggerated - and therefore false - mysticism, the systems of religious pragmatism and sentimentalism, so common outside the Church, are the more or less direct descendants.
From all such attempts to disparage the powers of human reason the Catholic Church has ever remained aloof. The Church, in thus vindicating the power of human reason to know God, is but reaffirming what St. Paul had said in his epistle to the Romans: “The invisible things of him, from the creation of the world, are clearly seen, being understood by the things that are made.”
But while the Church is solicitous to vindicate the just rights of the human reason, while she has no sympathy with those who unduly disparage it, she strenuously resists the claim of Rationalism that is "the sole judge of the true and false . . . that it is a law to itself and sufficient by its natural powers to procure the good of men and peoples. The Church asserts the essential soundness of the human mind and its radical capacity for learning all natural truth; but she is mindful that man is in a fallen state, that disordered passion and the manifold distractions of material things hamper and retard him in his pursuit of religious knowledge.
Human reason is a gift from God which separates us from animals not a whore as you and Luther proclaim. Try using it sometimes.
