Rome by degrees emerged from this equality, not by the splendid talents of any illustrious man, for among her early bishops none rose above mediocrity, but partly from her political position, partly from the great wealth she soon accumulated, and partly from the policy she happened to follow. Her bishop was not present at the Council of Nicea, A.D. 325, nor at that of Sardica, A.D. 345; perhaps on these occasions, as on others of a like kind subsequently, the immediate motive of his standing aloof was the fear that he might not receive the presidency. Soon, however, was discerned the advantage of the system of appearing by representatives. Such an attitude, moreover, offered the opportunity of frequently holding the balance of power in the fierce conflicts that soon arose, made Rome a retreat for the discomfited ecclesiastic, and her bishop, apparently, an elevated and unbiased arbiter on his case. It was thus that Athanasius, in his contests with the emperor, found a refuge and protector. With this elevated position in the esteem of strangers came also domestic dignity. The prodigal gifts of the rich Roman ladies had already made the bishopric to be sought after by those who esteem the ease and luxuries of life, as well as by the ambitious. Fierce contests arose on the occurrence of vacancies. At the election of Damasus, one hundred and thirty of the slain lay in the basilica of Sisinnius: the competitors had called in the aid of a rabble of gladiators, charioteers, and other ruffians; nor could the riots be ended except by the intervention of the imperial troops. [Sidenote: and early corruptions.] It was none too soon that Jerome introduced the monastic system at Rome--there was need of a change to austerity; none too soon that legacy-hunting on the part of the clergy was prohibited by law--it had become a public scandal; none too soon that Jerome struggled for the patronage of the rich Roman women; none too soon that this stern fanatic denounced the immorality of the Roman clergy, when even the Bishop Damasus himself was involved in a charge of adultery. It became clear, if the clergy would hold their ground in public estimation against their antagonists the monks, that celibacy must be insisted on. The doctrine of the pre-eminent value of virginity was steadily making progress; but it cost many years of struggle before the monks carried their point, and the celibacy of the clergy became compulsory. [Sidenote: Necessity for an apostolic head.] It had long been seen by those who hoped for Roman supremacy that there was a necessity for the establishment of a definite and ascertained doctrine--a necessity for recognizing some apostolic man, who might be the representative of a criterion of truth. The Eastern system of deciding by councils was in its nature uncertain. The councils themselves had no ascertained organization. Experience had shown that they were too much under the control of the court at Constantinople.
