Pius XII, 1939-

of God, that much more diminish human reason; and the more they exalt the authority of God who reveals, the more sharply they spurn the magisterium of the Church, instituted by Christ the Lord to guard and interpret the truths revealed by God. This indeed is not only in open contradiction to Sacred Scripture, but is proved false from actual experience. Often the very ones who disagree with the true Church openly complain about their own discord in matters of dogma, so that they unwillingly confess to the necessity of the living magisterium.

2308. Indeed, Catholic theologians and philosophers, upon whom falls the serious duty of protecting divine and human truth, and of inculcating these in the minds of men, may not ignore or neglect these opinions which more or less stray from the straight road. Moreover, they should thoroughly examine these opinions, because diseases cannot be cured unless they have been rightly diagnosed; also because sometimes in false fabrications something of truth lies hidden; finally, because such theories provoke the mind to scrutinize and weigh certain truths, philosophical or theological, more carefully.

But, if our philosophers and theologians strive to gather only such fruit from these doctrines, after cautious examination, there would be no reason for the intervention of the magisterium of the Church. However, although We have found that Catholic doctors in general are on their guard against those errors, yet it is well established that there are not lacking today, just as in apostolic times, those who, in their extreme zeal for novelty and also in their fear of being held ignorant of those matters which the science of a progressive age has introduced, strive to withdraw themselves from the temperateness of the sacred magisterium; and thus they become involved in the danger of gradually and imperceptibly departing from the truth revealed by God, and of leading others into error along with themselves.

Indeed, even another danger is observed, and is more serious, since it is more concealed under the appearance of virtue. There are many who, deploring the discord of the human race and the confusion of minds, and roused by an imprudent zeal for souls, are moved by a kind of impulse, and burn with a vehement desire to break down the barriers by which good and honest men are mutually separated, embracing such an irenicism that, forgetting the questions that separate men, they not only seek to refute destructive atheism by common strength, but even to reconcile opposing ideas in dogmatic matters. And just as once there were those who asked whether the traditional study of apologetics constituted an obstacle rather than an aid to the winning of souls for Christ, so today there are not lacking those who dare proceed to the point of seriously raising the question whether theology and its method, as they flourish in the schools with the approval of ecclesiastical authority, ought not
