From the thirty-eight propositions of the XIIIth Ordinary General Assembly of the Synod of Bishops in Rome, October 2012:
The worthy celebration of the Sacred Liturgy, God’s most treasured gift to us, is the source of the highest expression of our life in Christ (cf. Sacrosanctum concilium, 10).

God desires to manifest the incomparable beauty of his immeasurable and unceasing love for us through the Sacred Liturgy, and we, for our part, desire to employ what is most beautiful in our worship of God in response to his gift. In the marvelous exchange of the Sacred Liturgy, by which heaven descends to earth, salvation is at hand, calling forth repentance and conversion of heart (cf. Mt 4:17; Mk 1:15).
