Day 342: Trinitarian Prayer

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. CCC 2663

In today's reading, the Catechism discusses Trinitarian prayer in the Church. Specifically, prayer to the Father through the name of Jesus Christ, and the role of the Holy Spirit in our prayers.

The Catechism Compendium summarizes the way of our prayer and the role of the Holy Spirit in prayer:

The way of our prayer is Christ because prayer is directed to God our Father, but reaches him only if we pray – at least implicitly – in the name of Jesus. His humanity is, in effect, the only way by which the Holy Spirit teaches us to pray to our Father. Therefore, liturgical prayers conclude with the formula: “Through our Lord Jesus Christ.” Since the Holy Spirit is the interior Master of Christian prayer and “we do not know how to pray as we ought” (Rom 8:26), the Church exhorts us to invoke him and implore him on every occasion: “Come, Holy Spirit!” (#560-61)

The Catechism Companion Vol III has some good commentary on this:

Many alternative forms of "meditation" are promoted in our world and have often usurped the role of Christian prayer. We have to realize that if there is a prayer that does not involve Christ, then it is not Christian prayer. In the Mass, we are offering the sacrifice of the Son to the Father in the power of the Holy Spirit. The three Persons of the Trinity are inseparable, but at times we might focus on one Person of the Trinity in prayer. (p. 200)
