Excerpts from the Catechism of the Catholic Church

2724 Contemplative prayer is the simple expression of the mystery of prayer. It is a gaze of faith fixed on Jesus, an attentiveness to the Word of God, a silent love. It achieves real union with the prayer of Christ to the extent that it makes us share in his mystery.

III. Contemplative Prayer

2709 What is contemplative prayer? St. Teresa answers: "Contemplative prayer [oracion mental] in my opinion is nothing else than a close sharing between friends; it means taking time frequently to be alone with him who we know loves us." Contemplative prayer seeks him "whom my soul loves." It is Jesus, and in him, the Father. We seek him, because to desire him is always the beginning of love, and we seek him in that pure faith which causes us to be born of him and to live in him. In this inner prayer we can still meditate, but our attention is fixed on the Lord himself.

2710 The choice of the time and duration of the prayer arises from a determined will, revealing the secrets of the heart. One does not undertake contemplative prayer only when one has the time: one makes time for the Lord, with the firm determination not to give up, no matter what trials and dryness one may encounter. One cannot always meditate, but one can always enter into inner prayer, independently of the conditions of health, work, or emotional state. the heart is the place of this quest and encounter, in poverty ant in faith.

2711 Entering into contemplative prayer is like entering into the Eucharistic liturgy: we "gather up:" the heart, recollect our whole being under the prompting of the Holy Spirit, abide in the dwelling place of the Lord which we are, awaken our faith in order to enter into the presence of him who awaits us. We let our masks fall and turn our hearts back to the Lord who loves us, so as to hand ourselves over to him as an offering to be purified and transformed.

2712 Contemplative prayer is the prayer of the child of God, of the forgiven sinner who agrees to welcome the love by which he is loved and who wants to respond to it by loving even more.  But he knows that the love he is returning is poured out by the Spirit in his heart, for everything is grace from God. Contemplative prayer is the poor and humble surrender to the loving will of the Father in ever deeper union with his beloved Son.

2713 Contemplative prayer is the simplest expression of the mystery of prayer. It is a gift, a grace; it can be accepted only in humility and poverty. Contemplative prayer is a covenant relationship established by God within our hearts. Contemplative prayer is a communion in which the Holy Trinity conforms man, the image of God, "to his likeness."

2714 Contemplative prayer is also the pre-eminently intense time of prayer. In it the Father strengthens our inner being with power through his Spirit "that Christ may dwell in (our) hearts through faith" and we may be "grounded in love."

2715 Contemplation is a gaze of faith, fixed on Jesus. "I look at him and he looks at me": this is what a certain peasant of Ars used to say to his holy cure about his prayer before the tabernacle. This focus on Jesus is a renunciation of self. His gaze purifies our heart; the light of the countenance of Jesus illumines the eyes of our heart and teaches us to see everything in the light of his truth and his compassion for all men. Contemplation also turns its gaze on the mysteries of the life of Christ. Thus it learns the "interior knowledge of our Lord," the more to love him and follow him.

2716 Contemplative prayer is hearing the Word of God. Far from being passive, such attentiveness is the obedience of faith, the unconditional acceptance of a servant, and the loving commitment of a child. It participates in the "Yes" of the Son become servant and the Fiat of God's lowly handmaid.

2717 Contemplative prayer is silence, the "symbol of the world to come" or "silent love."  Words in this kind of prayer are not speeches; they are like kindling that feeds the fire of love. In this silence, unbearable to the "outer" man, the Father speaks to us his incarnate Word, who suffered, died, and rose; in this silence the Spirit of adoption enables us to share in the prayer of Jesus.

2718 Contemplative prayer is a union with the prayer of Christ insofar as it makes us participate in his mystery.  The mystery of Christ is celebrated by the Church in the Eucharist, and the Holy Spirit makes it come alive in contemplative prayer so that our charity will manifest it in our acts.

2719 Contemplative prayer is a communion of love bearing Life for the multitude, to the extent that it consents to abide in the night of faith.  The Paschal night of the Resurrection passes through the night of the agony and the tomb - the three intense moments of the Hour of Jesus which his Spirit (and not "the flesh [which] is weak") brings to life in prayer. We must be willing to "keep watch with (him) one hour.”

2725 Prayer is both a gift of grace and a determined response on our part. It always presupposes effort.  The great figures of prayer of the Old Covenant before Christ, as well as the Mother of God, the saints, and he himself, all teach us this: prayer is a battle. Against whom? Against ourselves and against the wiles of the tempter who does all he can to turn man away from prayer, away from union with God. We pray as we live, because we live as we pray. If we do not want to act habitually according to the Spirit of Christ, neither can we pray habitually in his name. the "spiritual battle" of the Christian's new life is inseparable from the battle of prayer.

2729 The habitual difficulty in prayer is distraction. It can affect words and their meaning in vocal prayer; it can concern, more profoundly, him to whom we are praying, in vocal prayer (liturgical or personal), meditation, and contemplative prayer. To set about hunting down distractions would be to fall into their trap, when all that is necessary is to turn back to our heart: for a distraction reveals to us what we are attached to, and this humble awareness before the Lord should awaken our preferential love for him and lead us resolutely to offer him our heart to be purified. Therein lies the battle, the choice of which master to serve.

More CCC on Prayer:

260 The ultimate end of the whole divine economy is the entry of God's creatures into the perfect unity of the Blessed Trinity. But even now we are called to be a dwelling for the Most Holy Trinity: "If a man loves me", says the Lord, "he will keep my word, and my Father will love him, and we will come to him, and make our home with him”:

O my God, Trinity whom I adore, help me forget myself entirely so to establish myself in you, unmovable and peaceful as if my soul were already in eternity. May nothing be able to trouble my peace or make me leave you, O my unchanging God, but may each minute bring me more deeply into your mystery! Grant my soul peace. Make it your heaven, your beloved dwelling and the place of your rest. May I never abandon you there, but may I be there, whole and entire, completely vigilant in my faith, entirely adoring, and wholly given over to your creative action. (Prayer of Blessed Elizabeth of the Trinity).

2014 Spiritual progress tends toward ever more intimate union with Christ. … God calls us all to this intimate union with him, even if the special graces or extraordinary signs of this mystical life are granted only to some for the sake of manifesting the gratuitous gift given to all.

2558  … 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  (St. John Damascene)

2560 "If you knew the gift of God!" The wonder of prayer is revealed beside the well where we come seeking water: there, Christ comes to meet every human being.  It is he who first seeks us and asks us for a drink. Jesus thirsts; his asking arises from the depths of God's desire for us. Whether we realize it or not, prayer is the encounter of God's thirst with ours. God thirsts that we may thirst for him. (St. Augustine)

2563 The heart is the dwelling-place where I am, where I live; …the heart is the place "to which I withdraw."  The heart is our hidden center, beyond the grasp of our reason and of others;  only the Spirit of God can fathom the human heart and know it fully.  … It is the place of encounter, because as image of God we live in relation: it is the place of covenant.

2564 Christian prayer is a covenant relationship between God and man in Christ.  It is the action of God and of man, springing forth from both the Holy Spirit and ourselves, wholly directed to the Father, in union with the human will of the Son of God made man.

2565 In the New Covenant, prayer is the living relationship of the children of God with their Father who is good beyond measure, with his Son Jesus Christ and with the Holy Spirit.  The grace of the Kingdom is "the union of the entire holy and royal Trinity . . . with the whole human spirit.” (St. Gregory of Nazianzus). Thus, the life of prayer is the habit of being in the presence of the thrice-holy God and in communion with him.

2567 … In prayer, the faithful God's initiative of love always comes first; our own first step is always a response. As God gradually reveals himself and reveals man to himself, prayer appears as a reciprocal call…

2570 …attentiveness of the heart, whose decisions are made according to God's will, is essential to prayer, while the words used count only in relation to it. 

2572 …Prayer restores man to God's likeness and enables him to share in the power of God's love that saves the multitude.

2573 …the spiritual tradition of the Church has retained the symbol of prayer as a battle of faith and as the triumph of perseverance.

2578 … "to stand before the LORD" … listen to his word: "Speak, LORD, for your servant is listening.”

2601 "He was praying in a certain place and when he had ceased, one of his disciples said to him, 'Lord, teach us to pray." In seeing the Master at prayer the disciple of Christ also wants to pray. By contemplating and hearing the Son, the master of prayer, the children learn to pray to the Father.

2602 Jesus often draws apart to pray in solitude, on a mountain, preferably at night.  … His words and works are the visible manifestation of his prayer in secret.

2607 When Jesus prays he is already teaching us how to pray. … Like a wise teacher he takes hold of us where we are and leads us progressively toward the Father…

2608 From the Sermon on the Mount onwards, Jesus insists on conversion of heart: … prayer to the Father in secret, not heaping up empty phrases

2609 Once committed to conversion, the heart learns to pray in faith. Faith is a filial adherence to God beyond what we feel and understand. It is possible because the beloved Son gives us access to the Father. He can ask us to "seek" and to "knock," since he himself is the door and the way.

2612 In Jesus "the Kingdom of God is at hand." He calls his hearers to conversion and faith, but also to watchfulness. In prayer the disciple keeps watch, attentive to Him Who Is and Him Who Comes, in memory of his first coming in the lowliness of the flesh, and in the hope of his second coming in glory. In communion with their Master, the disciples' prayer is a battle; only by keeping watch in prayer can one avoid falling into temptation.

2614 … Faith in the Son introduces the disciples into the knowledge of the Father, because Jesus is "the way, and the truth, and the life.”  Faith bears its fruit in love: it means keeping the word and the commandments of Jesus, it means abiding with him in the Father who, in him, so loves us that he abides with us. …

2615 Even more, what the Father gives us when our prayer is united with that of Jesus is "another Counselor, to be with you for ever, even the Spirit of truth…. In the Holy Spirit, Christian prayer is a communion of love with the Father, not only through Christ but also in him: "Hitherto you have asked nothing in my name; ask, and you will receive, that your joy may be full.

2616 …Jesus hears the prayer of faith, expressed in words (the leper, Jairus, the Canaanite woman, the good thief) or in silence (the bearers of the paralytic, the woman with a hemorrhage who touches his clothes, the tears and ointment of the sinful woman).  … St. Augustine wonderfully summarizes the three dimensions of Jesus' prayer: "He prays for us as our priest, prays in us as our Head, and is prayed to by us as our God. Therefore let us acknowledge our voice in him and his in us.”

2620 Jesus' filial prayer is the perfect model of prayer in the New Testament. Often done in solitude and in secret, the prayer of Jesus involves a loving adherence to the will of the Father even to the Cross and an absolute confidence in being heard.

2650 Prayer cannot be reduced to the spontaneous outpouring of interior impulse: in order to pray, one must have the will to pray. Nor is it enough to know what the Scriptures reveal about prayer: one must also learn how to pray. 

2651 The tradition of Christian prayer is one of the ways in which the tradition of faith takes shape and grows, especially through the contemplation and study of believers who treasure in their hearts the events and words of the economy of salvation, and through their profound grasp of the spiritual realities they experience.

2654 The spiritual writers, paraphrasing Matthew 7:7, summarize in this way the dispositions of the heart nourished by the word of God in prayer "Seek in reading and you will find in meditating; knock in mental prayer and it will be opened to you by contemplation.

2670 "No one can say 'Jesus is Lord' except by the Holy Spirit." Every time we begin to pray to Jesus it is the Holy Spirit who draws us on the way of prayer by his prevenient grace. Since he teaches us to pray by recalling Christ, 

2699 The Lord leads all persons by paths and in ways pleasing to him, and each believer responds according to his heart's resolve and the personal expressions of his prayer. However, Christian Tradition has retained three major expressions of prayer: vocal meditative, and contemplative. They have one basic trait in common: composure of heart. This vigilance in keeping the Word and dwelling in the presence of God makes these three expressions intense times in the life of prayer.

2704 Because it is external and so thoroughly human, vocal prayer is the form of prayer most readily accessible to groups. Even interior prayer, however, cannot neglect vocal prayer. Prayer is internalized to the extent that we become aware of him "to whom we speak;" Thus vocal prayer becomes an initial form of contemplative prayer.

2707 There are as many and varied methods of meditation as there are spiritual masters. … But a method is only a guide; the important thing is to advance, with the Holy Spirit, along the one way of prayer: Christ Jesus.

65 "In many and various ways God spoke of old to our fathers by the prophets, but in these last days he has spoken to us by a Son.” Christ, the Son of God made man, is the Father's one, perfect and unsurpassable Word. In him he has said everything; there will be no other word than this one. St. John of the Cross, among others, commented strikingly on Hebrews 1:1-2:

In giving us his Son, his only Word (for he possesses no other), he spoke everything to us at once in this sole Word - and he has no more to say. . . because what he spoke before to the prophets in parts, he has now spoken all at once by giving us the All Who is His Son. Any person questioning God or desiring some vision or revelation would be guilty not only of foolish behaviour but also of offending him, by not fixing his eyes entirely upon Christ and by living with the desire for some other novelty. (St. John of the Cross)

IN BRIEF
2720 The Church invites the faithful to regular prayer: daily prayers, the Liturgy of the Hours, Sunday Eucharist, the feasts of the liturgical year.
2721 The Christian tradition comprises three major expressions of the life of prayer: vocal prayer, meditation, and contemplative prayer. They have in common the recollection of the heart.
2722 Vocal prayer, founded on the union of body and soul in human nature, associates the body with the interior prayer of the heart, following Christ's example of praying to his Father and teaching the Our Father to his disciples.
2723 Meditation is a prayerful quest engaging thought, imagination, emotion, and desire. Its goal is to make our own in faith the subject considered, by confronting it with the reality of our own life.
2724 Contemplative prayer is the simple expression of the mystery of prayer. It is a gaze of faith fixed on Jesus, an attentiveness to the Word of God, a silent love. It achieves real union with the prayer of Christ to the extent that it makes us share in his mystery.

The wonder of prayer is revealed beside the well where we come seeking water: there, Christ comes to meet every human being. CCC2560
