The opening of Introduction
The attentive reader of history cannot fail to remark how often, in the confusion of the middle ages, the very movements or principles which seem in themselves most barbarous, or are most strongly tinctured with the darkest shades of superstition, have been those which, in the sequel, gave the strongest impulse to the advancing spirit of civilization which has at length changed that dark past into this bright present. It is in the contemplation of this oft-recurring fact, that we trace, more distinctly, perhaps, than in any other, the inscrutable but unerring ways of that higher Providence to whose rule all things are subjected. Few of those duties enjoined by the ancient Romish Church were accompanied with, and seemed to lead to, more abuses and scandals than the pilgrimages to the Holy Land, so natural an attraction to every Christian; few were attended with so much bigotry, and blindness, and uncharitableness, or ended in observances and convictions so grossly superstitious and so degrading to the intelligence of mankind.
