One of the most fundamental breaks with Catholic tradition was Luther’s rejection of reason, which reminds us so strongly of the acceptance of the “irrational values” by the National Socialists and their programmatic rejection of objective truth, an attitude they have in common with some of the pseudo-liberal philosophies. Luther was often moved by an irrational inspirationalism, disclaiming the possibility that anybody might correctly judge his doctrine—even the angels. Thus Hitler’s “sleepwalker’s certainty” (traumwandlerische Sicherheit) was anticipated by several centuries. We should therefore not be surprised by the declaration of the Reformer that it is impossible to harmonize faith and reason, that reason is opposed to faith and ought to be killed and interred, that there is nothing as contrary to faith as law and reason, and that those who want to enter Heaven must abandon, conquer, annihilate and destroy all reason.
