Liturgy and Doctrine: The Doctrinal Basis of the Liturgical Movement refers to a significant 1960 book by Charles Davis, exploring how Catholic worship (liturgy) reflects core beliefs (doctrine), especially focusing on the communal nature of Christ's priestly action in the Mass, aiming to foster deeper, informed participation, a key goal of the early 20th-century Liturgical Movement. This movement, rooted in monastic traditions, sought to revive active engagement with the Church's public worship, emphasizing the Mystical Body of Christ worshipping together.
