Even in Rome itself the point was still disputed. At that very time Gratian, the greatest canonist of the age, was engaged in the compilation of his “Concordia discordantium Canonum,” a work undertaken at the request of the papal curia to restore to the canon law the preëminence which it was fast losing in consequence of the recently revived study of the Justinian jurisprudence. Published in 1151 under the auspices of Eugenius himself, and presented to the world as the authoritative exposition of the laws and discipline of the church, it was everywhere received with acclamation, and has remained to this day the foundation of the canon law. Yet Gratian himself, in this work without appeal, distinctly declares his opposition to the doctrine of Innocent and Eugenius, asserting that a deacon can lawfully marry if he chooses to abandon the ministry, and that the sacrament of marriage is so potent that no antecedent vow can render it void.[788] The new law was long in winning its way to general respect, nor can it be a subject of wonder if those who disregarded the acknowledged canons of the church by marrying in orders, or by permitting such marriages in those under their charge, should neglect a rule of recent origin and of more than doubtful propriety. The church, however, was committed to it, and, moreover, could see in its eventual recognition a more effectual means of accomplishing the long desired object than in any expedient previously tried. By destroying all such marriages, pronouncing them null and void, inflicting an ineffaceable stigma on wife and offspring, subjecting the woman to the certainty of being cast off without resource and without option on the part of the husband, the position of the wife of an ecclesiastic would become most unenviable; her kindred would prevent her from exposing herself to such calamities, and no priest could succeed in finding a consort above the lowest class, whose union with him would expose him to the contempt of his flock.
