it Sunday extends back to the early days of the Church.
From Tertullian, it is plain that the festival was well known and long
established. In the _Peregrinatio Silviae_, we read a detailed account
of how the feast was kept in Jerusalem at her visit (385-388). "On the
night before Whitsunday the vigil was celebrated in the church of the
Anastasis, at which the bishop, according to the usual custom in
Jerusalem on Sundays, read the Gospel of the Resurrection, and the
customary psalmody was performed. At dawn, all the people proceeded to
the principal church (Martyrium) where a sermon was preached and Mass
celebrated. About the third hour, when the psalmody was finished, the
people singing accompanied the bishop to Sion. There, the passage from
the Acts of the Apostles describing the descent of the Holy Ghost was
read, and a second Mass was celebrated; after which the psalmody was
resumed. Afterwards, the archdeacon invited the people to assemble in
the 'Eleona,' from whence a procession was made to the summit of the
Mount of Olives. Here, psalms and antiphons were sung, the Gospel was
read and the blessing given. After this, the people descended again into
the 'Eleona,' where Vespers were sung, and then, with the bishop at
their head, proceeded in a solemn procession, with singing, back to the
principal church, which was reached towards 8 p.m. At the city gate the
procession was met by torch bearers, who accompanied it to the
Martyrium. Here, as well as in the Anastasias, to which the people
proceeded in turn, and in the chapel of the Holy Cross, the usual
prayers, hymns and blessings took place, so that the festival did not
conclude until midnight." (Kellner, _op. cit._, pp. 112-113). In most
churches, the principal services were solemn baptism and processions. In
some places it was customary to scatter roses from the roof of the
church, to recall the miracle of Pentecost. In France, trumpets were
blown in church, in memory of the great wind which accompanied the Holy
Spirit's descent.

TRINITY SUNDAY.

The first Sunday after Pentecost, for centuries, was not called Trinity
Sunday. Pope Alexander II. (circa 1073) was questioned about a feast in
honour of the Holy Trinity and he replied that it was not the Roman
custom to set apart any particular day in honour of the Trinity, which
was honoured many times daily in the psalmody, by the _Gloria Patri_.
