The sacred seasons, as they pass in orderly succession, give outward expression to the spirit which animates the Church, and are of the utmost importance from the point of view of her worship, since they form one of the chief elements in the instruction of mankind in the truths of Christianity. By them one easily becomes familiar with Christianity itself.
Every religion has its festivals, but none has so rich and so carefully thought out a system of feasts as the Catholic Church. If we may compare it to some artistically constructed edifice, we can regard the festivals of our Lord as forming the piers which support all the rest, the lesser feasts as contributing the decorations, and the Sundays, with their attendant weeks, as the stones of which the walls are built. Naturally all this did not exist at first, but, like many other things in the Church, has grown up into its present proportions from small beginnings.
We are not told that the Divine Founder of the Church appointed a single festival or left behind Him any instructions on the matter; still the germ, destined by Providence to develop afterwards into the system of festivals with which we are familiar, existed from the beginning. The subsequent rich and varied development of this system was not the work of individuals, but was due to the working of the spirit which ever rules the Universal Church, and ever renews itself within her. Love towards the Redeemer and gratitude for what He has done for us called the round of Christian festivals into being. The authorities in the Church have played the part of the gardener, pruning away superfluous shoots and branches. In view of the numerous institutions of this kind, some of which date back to remote antiquity, it was not a mere figure of speech which Tertullian made use of when, referring to the numerous heathen festivals, he addressed the Christians of his time with the words, “You have your own ‘fasti’” (“Habes tuos fastos.”—De Corona, c. 13).
The outline of the ecclesiastical year was prefigured in the Old Law, while the synagogue furnished the fundamental elements in its festivals, the Sabbath in particular, and in the division of the year into weeks. This renders a glance at the religious year of the Jews necessary, for, apart from it, it is impossible to understand the essential character of the Christian year.
The Jewish festivals in the time of Christ were instituted either in commemoration of events connected with the divine covenant, such as the Passover, or they were of an agrarian character or commemorated some national event, as the dedication of the Temple, Purim, Jom Kippar, etc.
According to the dates of their origin they fall into two classes:—
(a) The ancient festivals instituted by Moses: the Passover, the Feast of Weeks, in the earlier part of the year; the Feast of Trumpets, the Day of Atonement, and the Feast of Tabernacles, in autumn, i.e. on the first, seventh, and fifteenth days of the month Tizri.
(b) The more recent festivals instituted by the Synagogue, such as the Dedication of the Temple on the 25th Chisleu; Purim, or the Feast of Haman, on the 14th Adar. To these were added four fast days as days of national humiliation.
Consequently, since the death of Christ took place on the first day of the feast of the Passover (15th Nisan), and since the Descent of the Holy Ghost followed on the day of Pentecost, the chief Jewish feasts served as the foundation of the Christian ecclesiastical year, and the Apostles could join with the Jews in their Passover celebration. Certainly the object of their feast was very different from that of the Jews, yet, outwardly there was no separation from the synagogue.
