From early times the psalms have been used in Christianity. No doubt they were used already by Mary, Jesus and the disciples in their daily prayers. In the gospels, Jesus himself quotes the psalms to show that he fulfils the scriptures, especially Ps 22 (Gk 21) about his Passion and Ps 110 (Gk 109) about his resurrection and exaltation. For centuries the psalms have been used to express the prayers of Christians in moments of crisis or joy. (RNJB p928)
The Psalms are some of the most beloved words in all of history providing promise, hope, comfort, courage, insight and praise.

Interpreting the psalms
'Forming a sort of prayer-history of Israel, the reflection of many different stages and aspects of revelation and of God's guidance of his people, the psalms can bring us to a sense of God's unfailing love in the face of human striving, stubbornness, failure and forgiveness, an expression of the faltering human response, now despairing, now devoted, to God's ever-watchful care and correction.' (RNJB p931)
