¶ 2632
Christian petition is centered on the desire and search for the Kingdom to come, in keeping with the teaching of Christ. There is a hierarchy in these petitions: we pray first for the Kingdom, then for what is necessary to welcome it and cooperate with its coming. This collaboration with the mission of Christ and the Holy Spirit, which is now that of the Church, is the object of the prayer of the apostolic community. It is the prayer of Paul, the apostle par excellence, which reveals to us how the divine solicitude for all the churches ought to inspire Christian prayer. By prayer every baptized person works for the coming of the Kingdom.
¶ 2633
When we share in God's saving love, we understand that every need can become the object of petition. Christ, who assumed all things in order to redeem all things, is glorified by what we ask the Father in his name. It is with this confidence that St. James and St. Paul exhort us to pray at all times.
¶ 2634
Intercession is a prayer of petition which leads us to pray as Jesus did. He is the one intercessor with the Father on behalf of all men, especially sinners. He is "able for all time to save those who draw near to God through him, since he always lives to make intercession for them." The Holy Spirit "himself intercedes for us . . . and intercedes for the saints according to the will of God."
¶ 2635
Since Abraham, intercession - asking on behalf of another has been characteristic of a heart attuned to God's mercy. In the age of the Church, Christian intercession participates in Christ's, as an expression of the communion of saints. In intercession, he who prays looks "not only to his own interests, but also to the interests of others," even to the point of praying for those who do him harm.
¶ 2636
The first Christian communities lived this form of fellowship intensely. Thus the Apostle Paul gives them a share in his ministry of preaching the Gospel but also intercedes for them. The intercession of Christians recognizes no boundaries: "for all men, for kings and all who are in high positions," for persecutors, for the salvation of those who reject the Gospel.
¶ 2637
Thanksgiving characterizes the prayer of the Church which, in celebrating the Eucharist, reveals and becomes more fully what she is. Indeed, in the work of salvation, Christ sets creation free from sin and death to consecrate it anew and make it return to the Father, for his glory. the thanksgiving of the members of the Body participates in that of their Head.
¶ 2638
As in the prayer of petition, every event and need can become an offering of thanksgiving. the letters of St. Paul often begin and end with thanksgiving, and the Lord Jesus is always present in it: "Give thanks in all circumstances; for this is the will of God in Christ Jesus for you"; "Continue steadfastly in prayer, being watchful in it with thanksgiving."
¶ 2639
Praise is the form of prayer which recognizes most immediately that God is God. It lauds God for his own sake and gives him glory, quite beyond what he does, but simply because HE IS. It shares in the blessed happiness of the pure of heart who love God in faith before seeing him in glory. By praise, the Spirit is joined to our spirits to bear witness that we are children of God, testifying to the only Son in whom we are adopted and by whom we glorify the Father. Praise embraces the other forms of prayer and carries them toward him who is its source and goal: the "one God, the Father, from whom are all things and for whom we exist."
