In the Encyclical Mediator Dei, We have explained at great length why the Church, through the course of the liturgical year, recalls to mind and represents before our eyes, in orderly fashion, all the mysteries of Jesus Christ and bids us celebrate the feasts of the Virgin Mary and of the Saints. Those lessons, which We there imparted to all Christians because they are eminently useful for all, should be especially meditated upon by you priests; you, who through the Sacrifice of the Eucharist and the Divine Office, play such an important role in the development of the liturgical cycle.
