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 devotions
Devotion to saints, with the Virgin Mary as the most prominent example, is a key characteristic of Roman Catholicism. Catholic devotions have various forms, ranging from formalized, multi-day prayers such as novenas to activities which do not involve any prayers, such as Eucharistic adoration outside Mass, the wearing of scapulars, the veneration of the saints, the Canonical coronations of sacred Marian or Christological images and even horticultural practices such as maintaining a Mary garden.
