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."
Mary, mother of Jesus
Although the Catholics and the Orthodox may honor and venerate Mary, they do not view her as divine, nor do they worship her. Roman Catholics view Mary as subordinate to Christ, but uniquely so, in that she is seen as above all other creatures. Similarly Theologian Sergei Bulgakov wrote that the Orthodox view Mary as "superior to all created beings" and "ceaselessly pray for her intercession". However, she is not considered a "substitute for the One Mediator" who is Christ. "Let Mary be in honor, but let worship be given to the Lord", he wrote. Similarly, Catholics do not worship Mary as a divine being, but rather "hyper-venerate" her. In Roman Catholic theology, the term "hyperdulia" is reserved for Marian veneration, "latria" for the worship of God, and "dulia" for the veneration of other saints and angels. The definition of the three level hierarchy of "latria", "hyperdulia" and "dulia" goes back to the Second Council of Nicaea in 787.
