It is a recognised fact in history that the festivals of the Church in the course of centuries considerably increased in number, and that, when this increase had reached its highest point, their number began again to diminish. This was partly effected by means of legislation and without disturbance, but partly by the violent proceedings attendant upon the French Revolution. The stages in this process will be best understood from an account of the secular and ecclesiastical legislation by which they were brought about. Tertullian[39] is the first ecclesiastical writer who enumerates the feasts celebrated among the Christians. The only festivals known to him, and to Origen after him, are Easter and Pentecost.[40] His statement is all the more noteworthy, because the exigencies of his controversy with Celsus required he should specify all the festivals by name. These are, besides Sundays, the Parasceve, Easter, and Pentecost. Tertullian and Origen are witnesses respectively for the East and West, and since their evidence coincides, it is certain that in the third century only the first germs existed of that Church-life which subsequently was to reach so rich a development. The cessation of persecution removed those hindrances which up to then had stood in the way of its evolution. The increase of festivals can now be traced with the assistance of secular legislation, inasmuch as the Christian Emperors prohibited the sitting of the law-courts and games in the circus on certain days. It has been already shown that Constantine, as early as 321, appointed that no legal business should be transacted on all Sundays of the year. In a proclamation concerning the regulation of legal vacations, put forth by Valentinian II. and his colleague in the Empire, and dated from Rome on the 7th August 389, the seven days before and after Easter are added to the Sundays.[41] In the same way as special sittings of the law-courts were abolished on Sundays, so, later on, the proceedings before the judge of arbitration were forbidden. When a day became recognised as exempt from legal business, this did not at once render it a festival or holy day, otherwise, according to the law of 389, there would have been fifteen consecutive holy days. The prohibition of legal proceedings in the courts on a given day, had regard, in the first place, to the removal of all hindrances which might interfere with attendance at divine worship on the part of those employed therein. In the second place, however, it must be remembered that in those days the sittings of the criminal courts almost always implied the application of torture; and such proceedings on holy days seemed especially out of place. This must also have been the reason why Valentinian and his colleague forbade prosecutions in the criminal courts throughout the whole of Lent. He certainly did not aim at changing all the days of Lent into feast-days. This law was renewed by Justinian.[42]
