The great work which pre-eminently called out his genius, and for which he would seem to have been raised up, was to combat the Pelagian heresy, and establish the doctrine of the necessity of Divine Grace,--even as it was the mission of Athanasius to defend the doctrine of the Trinity, and that of Luther to establish Justification by Faith. In all ages there are certain heresies, or errors, which have spread so dangerously, and been embraced so generally by the leading and fashionable classes, that they seem to require some extraordinary genius to arise in order to combat them successfully, and rescue the Church from the snares of a false philosophy. Thus Bernard was raised up to refute the rationalism and nominalism of Abélard, whose brilliant and subtile inquiries had a tendency to extinguish faith in the world, and bring all mysteries to the test of reason. The enthusiastic and inquiring young men who flocked to his lectures from all parts of Europe carried back to their homes and convents and schools insidious errors, all the more dangerous because they were mixed with truths which were universally recognized. It required such a man as Bernard to expose these sophistries and destroy their power, not so much by dialectical weapons as by appealing to those lofty truths, those profound convictions, those essential and immutable principles which consciousness reveals and divine authority confirms. It took a greater than Abélard to show the tendency of his speculations, from the logical sequence of which even he himself would have fled, and which he did reject when misfortunes had broken his heart, and disease had brought him to face the realities of the future life. So God raised up Pascal to expose the sophistries of the Jesuits and unravel that subtle casuistry which was undermining the morality of the age, and destroying the authority of Saint Augustine on some of the most vital principles which entered into the creed of the Catholic Church. Thus Jonathan Edwards, the ablest theologian which this country has seen, controverted the fashionable Arminianism of his day. Thus some great intellectual giant will certainly and in due time appear to demolish with scathing irony the theories and speculations of some of the progressive schools of our day, and present their absurdities and boastings and pretensions in such a ridiculous light that no man with any intellectual dignity will dare to belong to their fraternity, unless he impiously accepts--sometimes with ribald mockeries--the logical sequence of their doctrines.
