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."
Roman Catholic (term)
We use the term "Roman Catholic Worship" throughout to make it clear that we are not covering all forms of Catholic worship. There are a number of Eastern Rite churches that can justly claim the title "Catholic", but many of the statements we make do not apply to them at all.
Compared to the Roman Rite, the other Western liturgical rites have little following. Hence, the Vatican department that deals with forms of worship (including music) in the Western Church often issues documents that deal only with the Roman Rite.
