The impact of Christianity on the functioning of the later Roman empire has been examined by historians ever since Gibbon published his Decline and Fall. Had the Christians hastened the decline and fall of Rome? Outlining some themes of his projected work, Gibbon suggested before 1774 that indeed they had. In 1776, when publishing the first volume of his history, he touched on this same issue with considerable circumspection; but five years later, his earlier opinion appeared in print under the heading of “General Observations on the Decline of the Empire in the West” by way of concluding the third volume of the work. Here, Gibbon stated:
As the happiness of a future life is the great object of religion, we may hear, without surprise or scandal, that the introduction, or at least the abuse, of Christianity had some influence on the decline and fall of the Roman empire. The clergy successfully preached the doctrines of patience and pusillanimity; the active virtues of society were discouraged: and the last remains of military spirit were buried in the cloister; a large portion of public and private wealth was consecrated to the specious demands of charity and devotion; and the soldiers' pay was lavished on the useless multitudes of both sexes, who could only plead the merits of abstinence and chastity.
