The Church professes this mystery in the Apostles’ Creed (Part One) and celebrates it in the sacramental liturgy (Part Two), so that the life of the faithful may be conformed to Christ in the Holy Spirit to the glory of God the Father (Part Three).
This mystery, then, requires that the faithful believe in it, that they celebrate it, and that they live from it in a vital and personal relationship with the living and true God. This relationship is prayer.
What is prayer?
For me, prayer is a surge of the heart;
it is a simple look turned toward heaven,
it is a cry of recognition and of love,
embracing both trial and joy. (St. Therese of Lisieux)
2559 “Prayer is the raising of one’s mind and heart to God or the requesting of good things from God.” But when we pray, do we speak from the height of our pride and will, or “out of the depths” of a humble and contrite heart? He who humbles himself will be exalted; humility is the foundation of prayer, Only when we humbly acknowledge that “we do not know how to pray as we ought,” are we ready to receive freely the gift of prayer. “Man is a beggar before God.” (CCC)
