liturgy

Has two sets of meanings, one for Western Christians and the other for Eastern Christians. Among Roman Catholics and Protestants, lowercase liturgy means a standard set of prayers and practices for public worship. It can also be used as a synonym for the service of worship in churches that use such forms – most commonly the Catholic, Anglican and Lutheran. With reference to Orthodox Christians and Eastern Catholics, uppercase Liturgy; avoid the lowercase use of the word with their churches. Churches that tend to vary their services each week, such as most Baptist, Pentecostal and independent churches, are often called nonliturgical.
