"In the Church's liturgy the divine blessing is fully revealed and communicated. the Father is acknowledged and adored as the source and the end of all the blessings of creation and salvation. In his Word who became incarnate, died, and rose for us, he fills us with his blessings. Through his Word, he pours into our hearts the Gift that contains all gifts, the Holy Spirit."
Catechism of the Catholic Church 1082
Christian liturgy is a liturgy of promise fulfilled, of a quest, the religious quest of human history, reaching its goal. But it remains a liturgy of hope. It, too, bears within it the mark of impermanence. The new Temple, not made by human hands, does exist, but it is also still under construction. The great gesture of embrace emanating from the Crucified has not yet reached its goal; it has only just begun. Christian liturgy is liturgy on the way, a liturgy of pilgrimage toward the transfiguration of the world, which will only take place when God is 'all in all.'" —Joseph Cardinal Ratzinger, later Pope Benedict XVI, The Spirit of the Liturgy, 1999
