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 laity
The Catholic Church is served by the universal jurisdiction of the Holy See, headed by the Pope, and administered by the Roman Curia, while locally served by diocesan bishops. The Pope and the bishops in full communion with him are known collectively as the Catholic hierarchy, and are responsible for the supervision, management, and pastoral care of all members the Catholic Church, including clergy, religious, and laity. But since the Second Vatican Council of Bishops (1962-1965) the laity have emerged as a greater source of leadership in various aspects of the church's life; and its teaching on their equal call to holiness has led to greater recognition of their role in the church.
