The Revised Common Lectionary is a lectionary of readings or pericopes from the Bible for use in Protestant Christian worship, making provision for the liturgical year with its pattern of observances of festivals and seasons. It was preceded by the Common Lectionary, assembled in 1983, itself preceded by the COCU Lectionary, published in 1974 by the Consultation on Church Union (COCU). This lectionary was derived from various Protestant lectionaries in current use, which in turn were based on the 1969 Ordo Lectionum Missae, a three-year lectionary produced by the Roman Catholic Church following the reforms of the Second Vatican Council.
The Revised Common Lectionary was the product of a collaboration between the North American Consultation on Common Texts (CCT) and the International English Language Liturgical Consultation (ELLC). After a nine-year trial period, it was publicly released in 1994. The CCT membership includes the United States Conference of Catholic Bishops and the Canadian Conference of Catholic Bishops as well as many traditional liturgically-based American and Canadian Episcopal and Protestant Churches such as Lutheran, North American Anglican (Episcopal), Presbyterian, and more loosely Methodist. The CCT thereby represents the majority of American and Canadian Christians and has been widely adopted in Great Britain and in some countries such as Australia. Various Churches, however, have made some changes to the form of the RCL that they use.
