Easter to Pentecost_:--The
Resurrection, the Ascension, Pentecost.

_Fourth General Division, from Pentecost till Advent_, the
termination of the Church's year. The mystic life of Christ in the
Church, which will end on the Judgment Day.

These divisions make up the four parts of the Roman Breviary.

The first part, _Pars Prima_, contains the Pontifical Bull,
_Quod a nobis_, of Pope Pius V. (1568). It states:--1. That the
cause of the new edition was to remove the regrettable variety in the
public liturgy. 2. It recalls the labours of Pope Paul IV., Pius IV.,
and Pius V. for the same end. 3. It announces the abolition of the
too-abbreviated Breviary of Quignonez and of all those which have not,
for two hundred years preceding 1568, an authentic approbation or a
lawful custom. 4. It gives permission to those using such breviaries
to adopt the Roman Breviary. 5. It withdraws all privileges in respect
to other breviaries. 6. It declares the Roman Breviary obligatory on all

obligation of those bound to breviary recitation. 9. Bishops are
requested to introduce the new Breviary. 10. The Pope suppressed the
obligation of reciting on certain days the little Office of the Blessed
Virgin, the Office of the Dead, the Penitential and the Gradual Psalms,
11. But he recommends their recitation on certain fixed days and grants
an indulgence for the practice. 12. Where the custom of reciting the
little Office, in choir, exists, it should be retained. 13. The
appointment of the time for the adoption of the Breviary is obligatory.
14. Prohibition, under pain of excommunication, is made against those
who print, distribute or receive copies of this Breviary without lawful
authority. 15. The authentic publication and obligation of the Bull.

The second document in the _Pars Prima_ of the Roman Breviary is
the Bull _Divino Afflatu_, issued by Pope Pius X, on 1st November,
1911. It tells us:--

1. That the psalms were composed under divine inspiration, and that it
is well known that from the beginning of the Church they were used not
only to foster the piety of the faithful, who offered "the sacrifice of
praise to God, that is to say, the fruit of lips confessing to His name"
(Heb. xiii. 15), but--that retaining the custom of the Old Law--they
