Christian worship

In Christianity, worship is the act of attributing reverent honour and homage to God.[1] In the New Testament, various words are used to refer to the term worship. One is proskuneo ("to worship") which means to bow down to God or kings.[2]

Throughout most of Christianity's history, corporate Christian worship has been liturgical, characterized by prayers and hymns, with texts rooted in, or closely related to, the Scripture, particularly the Psalter; this form of sacramental and ceremonial worship is still practiced by the Roman Catholic, Eastern Orthodox, and Anglican churches, as well as some Protestant denominations such as Lutheranism and Methodism. In Evangelicalism, worship is viewed like an act of adoration of God, with a more informal conception.

The term liturgy is derived from the Greek leitourgia meaning "public service" and is formed by two words: "laos" (people) and "ergon" (work), literally "work of the people". Responsorial prayers are a series of petitions read or sung by a leader with responses made by the congregation. Set times for prayer during the day were established (based substantially on Jewish models), and a festal cycle throughout the Church year governed the celebration of feasts and holy days pertaining to the events in the life of Jesus, the lives of the saints, and aspects of the Godhead.

A great deal of emphasis was placed on the forms of worship, as they were seen in terms of the Latin phrase lex orandi, lex credendi ("the rule of prayer is the rule of belief")—that is, the specifics of one's worship express, teach, and govern the doctrinal beliefs of the community. According to this view, alterations in the patterns and content of worship would necessarily reflect a change in the faith itself. Each time a heresy arose in the Church, it was typically accompanied by a shift in worship for the heretical group. Orthodoxy in faith also meant orthodoxy in worship, and vice versa. Thus, unity in Christian worship was understood to be a fulfillment of Jesus' words that the time was at hand when true worshipers would worship "in spirit and in truth" (John 4:23).
