The correct answer is liturgy.
Liturgy is the public worship performed by a religious group. It comes from the Greek word 'leitourgia' which describes the work of an individual in service to God.
Liturgy is a prescribed ritual that many churches use in their services and in their ceremonial rites. It can include all forms of services ( prayers, songs, chanted commentaries, poems, hymns, offering, gospel, sermon etc. ) used during a religious service, especially the mass.
The purpose of any kind of liturgy is to hear God's message and to get it across to the people attending the service. Liturgy uses the Bible as it was first intended: to hear God's words directly and to respond to the words by praying.
