“The importance of music in biblical religion is shown very simply by the fact that the verb “to sing” (with related words such as “song”, and so forth) is one of the most commonly used words in the Bible. It occurs 309 times in the Old Testament and thirty-six in the New. When man comes into contact with God, mere speech is not enough.  Areas of his existence are awakened that spontaneously turn into song. Indeed, man’s own being is insufficient for what he has to express, and so he invites the whole of creation to become a song with him: “Awake, my soul! Awake, O harp and lyre! I will awake the dawn!”

The singing of the Church comes ultimately out of love. It is the utter depth of love that produces the singing. “Cantare amantis est”, says St Augustine, singing is a lover’s thing. In so saying, we come again to the trinitarian interpretation of Church music. The Holy Spirit is love, and it is he who produces the singing. He is the Spirit of Christ, the Spirit who draws us into love for Christ and so leads to the Father.

In liturgical music, based as it is on biblical faith, there is, therefore, a clear dominance of the Word; this music is a higher form of proclamation. Ultimately, it rises up out of the love that responds to God’s love made flesh in Christ, the love that for us went unto death.’
