In the middle ages, the anniversary of the dedication (_natale ecclesiæ_) was observed as a general festival of obligation for the local congregation irrespective of whether it fell on a week-day or on a Sunday; it was also to be observed with an octave.[441] In Germany it was ordered by the Synod of Mainz in 813, and, along with the feast of the Patron Saint, in the statute of Bishop Hetto of Basel about 827. Both festivals are found together in the statutes of Lanfranc of Canterbury and in the decrees of the Council of Szabolcs in Hungary, in 1092. The ecclesiastical celebration consisted of a vigil, solemn High Mass, and procession in which the relics of the saints belonging to the church were carried. A flag was wont to fly from the church tower, the floor was strewn with green leaves, the altar and pulpit were decorated with boughs, and a bunch of flowers was placed before the picture of the Patron Saint. The anniversary of the dedication of each altar was also observed, but only inside the walls of the church.[442] Festivals of the Patron Saints were not enjoined as of obligation in the decretal of Gregory IX. in 1232, although placed by Lanfranc in the highest class of feasts. They were regarded as such in various countries, especially throughout Germany. Thus, the diocesan Synod of Cologne, under Archbishop Heinrich II., placed them along with the dedication of churches among the holy days of obligation,[443] and so also did the statute of Archbishop Baldwin of Treves in 1338. On the other hand, the provincial Synod of Cologne in 1549, under Adolf III., expressly suppressed them as holy days of obligation, and desired they should be celebrated only in choir, in order, as it said, festivals should not become too numerous. It also forbade noisy revels, such as dancing, etc., at the festival of the dedication of a church. To have a church of its own, especially a parish church, was of the greatest importance to each district, on account of the spiritual and even material benefits of which it was the source. This explains the enthusiasm with which the dedication of the church was observed. With the ecclesiastical festival were soon associated secular amusements, fairs, merry-makings, and shows. The dedication was especially the festival of the people in the middle ages, and, as always happens in such cases, the secular influences proved stronger than the spiritual, although the dedication was one of the days on which indulgences were usually granted. As parishes and churches became more numerous, the number of these festivals increased also, and the result was that not only the parish in question observed the feast, but all the neighbouring parishes joined in the celebration. Thus these feasts and the merry-making associated with them increased without limit. Among the country people especially it was inevitable that excess and licence should give rise to grave disorders.
