The Sacred Liturgy, declares Vatican II, is the font from which all the Church's spiritual power flows. In his modern classic work The Wellspring of Worship, Fr. Jean Corbon explores the meaning of the Liturgy as the "wellspring" or source of the Church's life and worship of God. The Liturgy itself is a sharing in the mystery of the Triune God and in the Incarnation, Passion, Death, Resurrection and Ascension of Jesus. Corbon writes that it is "the mystery of the river of life that streams from the Father and the Lamb", into which believers are to be drawn. In this way, the divine river waters their entire lives, renewing and transforming them.

The Wellspring of Worship is a masterful reflection on the mystery of God's Trinitarian life and how the Church's members participate in that life through the Liturgy.
