Catholic theology
Catholic belief holds that the church exists both on earth and in heaven simultaneously, and thus the Virgin Mary and the saints are alive and part of the living church. Prayers and devotions to Mary and the saints are common practices in Catholic life. These devotions are not worship, since only God is worshiped. The church teaches that the saints "do not cease to intercede with the Father for us. ... So by their fraternal concern is our weakness greatly helped."
Catholic Church
Devotions are "external practices of piety" which are not part of the official liturgy of the Catholic Church but are part of the popular spiritual practices of Catholics. These include various practices regarding the veneration of the saints, especially veneration of the Virgin Mary. Other devotional practices include the Stations of the Cross, the Sacred Heart of Jesus, the Holy Face of Jesus, the various scapulars, novenas to various saints, pilgrimages and devotions to the Blessed Sacrament, and the veneration of saintly images such as the "santos". The bishops at the Second Vatican Council reminded Catholics that "devotions should be so drawn up that they harmonise with the liturgical seasons, accord with the sacred liturgy, are in some fashion derived from it, and lead the people to it, since, in fact, the liturgy by its very nature far surpasses any of them."
