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)
"In popular usage, 'Catholic' usually means 'Roman Catholic'," a usage opposed by some, including some Protestants. "Catholic" usually refers to members of any of the 24 constituent Churches, the one Western and the 23 Eastern. The same meaning is attributed also to "Roman Catholic" in older documents of the Holy See, talks by Popes and in newspapers.
