Roman Catholic devotions are “external practices” which are not part of the official liturgy of the Catholic Church. These devotions are a part of the popular spiritual practices of many Catholics. Catholic devotions do not become part of the liturgy even when it is performed in the presence of a priest. The Congregation for Divine Worship publishes a Directory on Popular Piety and Liturgy.
Common examples of Catholic devotions include but are not limited to: the Rosary, the Stations of the Cross, wearing of scapulars, Novenas to various saints, and Adoration of the Blessed Sacrament.
