Fr Pius Parsch, one of the most eminent members of the original Liturgical Movement, furnishes us in this book with an unmatched guide to the riches of the (preconciliar) Breviary of the Catholic Church. To quote from the author himself:

"The Breviary is the official prayerbook of the Church. The Holy Ghost and the Church have been working on it for more than 3,000 years, and it has become the basic book of prayer, a precious common fund to which the great men of prayer from every age have contributed their thoughts and sentiments. The two chief objectives which the breviary fulfills are: it is the prayer of the Church as a body, and it is a guide to genuine spiritual growth for the individual soul.

"In private prayer I pray, mostly, for myself and my own affairs. It is the isolated person who stands in the centre of the action, and the prayer is more or less individualized. But in liturgical prayer, and therefore in the breviary, it is not primarily I who am praying, but the Church, the bride of Christ. The object of her prayer is broader, too: all the needs of God's kingdom here on earth. In liturgical prayer, I feel more like a member of a great community, like a little leaf on the great living tree of the Church. I share her life and her problems.

"The Church is praying through my mouth, I offer her my tongue to pray with her for all the great objectives of redemption, and for God's honour and glory. We weep, too, or rather the Church weeps through our tears, together with those who weep, rejoices through our joys together with those who rejoice, does penance with the repentant. All the sentiments of Holy Mother Church find their echo in our heart. This gives a deeper content to our prayer; we spread out far beyond our own selves.

"Breviary and Mass belong together; they form a unity, the liturgical day. We might compare the relationship to the sun and the planets. The Mass is the sun about which the planets, that is, the canonical hours, gravitate. The canonical hours prepare for the Mass, they surround the Mass, they try to realize and retain the fruits of the Mass, and spread them over the day."
