Jesus' teaching on prayer in the Sermon on the Mount displays a distinct lack of interest in the external aspects of prayer. A concern with the techniques of prayer is condemned as 'pagan', and instead a simple trust in God's fatherly goodness is encouraged.[Mat. 6:5–15] Elsewhere in the New Testament this same freedom of access to God is also emphasized.[Phil. 4:6][Jam. 5:13–19] This confident position should be understood in light of Christian belief in the unique relationship between the believer and Christ through the indwelling of the Holy Spirit. In subsequent Christian traditions, certain physical gestures are emphasized, including medieval gestures such as genuflection or making the sign of the cross. Kneeling, bowing and prostrations (see also poklon) are often practiced in more traditional branches of Christianity. Frequently in Western Christianity the hands are placed palms together and forward as in the feudal commendation ceremony. At other times the older orans posture may be used, with palms up and elbows in. Intercessory prayer is prayer offered for the benefit of other people. There are many intercessory prayers recorded in the Bible, including prayers of the Apostle Peter on behalf of sick persons[Acts 9:40] and by prophets of the Old Testament in favor of other people.[1Ki 17:19–22] In the New Testament book of James no distinction is made between the intercessory prayer offered by ordinary believers and the prominent Old Testament prophet Elijah.[Jam 5:16–18] The effectiveness of prayer in Christianity derives from the power of God rather than the status of the one praying. The ancient church, in both Eastern Christianity and Western Christianity, developed a tradition of asking for the intercession of (deceased) saints, and this remains the practice of most Eastern Orthodox, Oriental Orthodox, Roman Catholic, and some Anglican churches. Churches of the Protestant Reformation however rejected prayer to the saints, largely on the basis of the sole mediatorship of Christ. The reformer Huldrych Zwingli admitted that he had offered prayers to the saints until his reading of the Bible convinced him that this was idolatrous.
According to the Catechism of the Catholic Church: "Prayer is the raising of one's mind and heart to God or the requesting of good things from God." The Book of Common Prayer in the Anglican tradition is a guide which provides a set order for church services, containing set prayers, scripture readings, and hymns or sung Psalms.
