Article 1 IN THE OLD TESTAMENT

From The Catechism of the Catholic Church

2588
The Psalter’s many forms of prayer take shape both in the liturgy of the Temple
and in the human heart. Whether hymns or prayers of lamentation or
thanksgiving, whether individual or communal, whether royal chants, songs of
pilgrimage or wisdom meditations, the Psalms are a mirror of God’s marvelous
deeds in the history of his people, as well as reflections of the human
experiences of the Psalmist. Though a given psalm may reflect an event of the
past, it still possesses such direct simplicity that it can be prayed in truth
by men of all times and conditions.
