51 This is a state of mind which demands, in special degree, our tears and groans, and has often stirred my pity, from the conviction that imagination robs us in great measure of reality, and that vain glory is a great hindrance to men's attainment of virtue. To heal and stay this disease needs a Peter or Paul, those great disciples of Christ, who in addition to guidance in word and deed, received their grace, and became all things to all men, that they might gain all. But for other men like ourselves, it is a great thing to be rightly guided and led by those who have been charged with the correction and setting right of things such as these.
