Pope Francis spoke of the “Opening Prayer,” the last of the “Introductory Rites” of the Mass, in his catechesis on the Mass on January 10, 2018:
“…Prayer takes on a particular form in the oration known as the ‘collect’, through which the very character of the celebration is expressed, with variations according to the days and time of the year. With the invitation ‘Let us pray,’ the priest encourages the people to recollect themselves with him in a brief silence, so that they may be conscious that they are in God’s presence and so that all can formulate within their own heart the personal petitions with which they are participating in the Mass….
The silence is not confined to the absence of words but rather to preparing oneself to listen to other voices: the one in our heart and, above all, the voice of the Holy Spirit…. Thus, before the opening prayer, silence helps us to recollect ourselves and to contemplate why we are there. This, then, is the importance of listening to our heart, so as to then open it to the Lord. Perhaps we have experienced days of toil, of joy, of pain, and we want to tell the Lord about it, to invoke his help, to ask that he be at our side; we may have relatives and friends who are ill or who are undergoing difficult trials; we may wish to entrust to God the future of the Church and the world….
The priest recites this plea, this collect prayer, with outstretched arms …. to imitate Christ with his arms outstretched on the wood of the Cross. And there, Christ is both the One praying and also the Prayer! In the Crucifix, we recognize the Priest who offers God the worship He cherishes, namely, filial obedience.
Prayers in the Roman Rite are concise but rich in meaning. One can have beautiful meditations on these prayers. Very beautiful! Returning to meditate on these texts, even outside the Mass, can help us understand how to address God, what to ask and which words to use. May the Liturgy become for all of us a true school of prayer.” (Pope Francis, General Audience, January 10, 2018)
