Chapter 26 — Part III: The Decalogue — The Third Commandment
Section 33. Other Festivals Observed By The Church — From the very infancy of the Church and in the following centuries other days were also appointed by the Apostles and the holy Fathers, in order to commemorate the benefits bestowed by God. Among these days to be kept sacred the most solemn are those which were instituted to honour the mysteries of our redemption. In the next place are the days which are dedicated to the most Blessed Virgin Mother, to the Apostles, Martyrs and other Saints who reign with Christ. In the celebration of their victories the divine power and goodness are praised, due honour is paid to their memories, and the faithful are encouraged to imitate them.
