The Liturgical Movement is a 20th-century initiative within the Christian church aimed at revitalizing worship practices. It emphasizes the importance of communal worship, encouraging active participation from the congregation rather than passive observation. This movement seeks to deepen the spiritual experience through a more meaningful engagement with the liturgy. Key figures in the movement include Dom Gregory Dix and Pope Pius XII, who advocated for reforms in the celebration of the sacraments and the use of vernacular languages in worship. The movement has influenced various denominations, leading to changes in how liturgical texts and rituals are understood and practiced today.
