"Dear friends, we celebrate and live the liturgy well only if we remain in a prayerful attitude, and not if we want "to do something," to make ourselves seen or to act, but if we direct our hearts to God and remain in a prayerful attitude, uniting ourselves with the Mystery of Christ and with his conversation as Son with the Father. God himself teaches us to pray, Saint Paul says cf. Rom 8:26. He himself gave us the appropriate words with which to address him, words that we find in the Psalter, in the great orations of the sacred liturgy and in the Eucharistic celebration itself. Let us pray the Lord to be every day more aware of the fact that the liturgy is an action of God and of man; prayer that wells up from the Holy Spirit and from us, wholly directed to the Father, in union with the Son of God made man." Pope Benedict XVI, general audience September 26, 2012.
