In the living tradition of prayer, each Church proposes to its faithful, according to its historic, social, and cultural context, a language for prayer: words, melodies, gestures, iconography. The Magisterium of the Church has the task of discerning the fidelity of these ways of praying to the tradition of apostolic faith; it is for pastors and catechists to explain their meaning, always in relation to Jesus Christ.
