What the rule of celibacy was at this period, in England, seems uncertain. Lingard maintains that marriage was always permitted to the clergy in minor orders, who were employed in various subordinate positions, but that those in higher orders, whose office it was to minister at the altar and to offer the sacrifice, were expressly bound to a life of the strictest continence. During the invasion of the Danes, when confusion reigned, many priests in the higher orders had not only forsaken their vows of chastity, but had plunged into frightful immoralities; and married clerks of inferior orders were raised to the priesthood to fill the ranks depleted by war. These promoted clerks were previously required to separate from their wives, but apparently many of them did not do so. Consequently, from several causes, the married priests became a numerous body, and since the common opinion seems to have been that a married priest was disgracing his office, this body was regarded as a menace to the welfare of the church and the state. Lea, in his elaborate "History of Sacerdotal Celibacy," holds that the rule of celibacy was only binding on the regulars, or monks, and that the secular priesthood was at liberty to marry. But from several other passages in his work it seems that he also recognizes the fact that, while marriage was common, it was in defiance of an ancient canon. "It is evident," he says, "that the memory of the ancient canons was not forgotten, and that their observance was still urged by some ardent churchmen, but that the customs of the period had rendered them virtually obsolete, and that no sufficient means existed of enforcing obedience. If open scandals and shameless bigamy and concubinage could be restrained, the ecclesiastical authorities were evidently content. Celibacy could not be enjoined as a law, but was rendered attractive by surrounding it with privileges and immunities denied to him who yielded to the temptations of the flesh." Throughout Western Christendom the law of celibacy was openly and shamefully trampled upon, and every reformer seemed to think that the very first step toward any improvement in clerical morals was to be taken by enforcing this rule. When Dunstan commenced his reforms, the clergy were guilty of graver sins than that of living in marriage relations. Adultery, bigamy, swearing, fighting and drinking were the order of the day. The monasteries were occupied by secular priests with wives or concubines. All the chroniclers of this period agree in charging the monks and clergy with a variety of dissipations and disorders.
