Vatican Council II was sensitive to the views of other Christians, as the council, at the request of Pope John XXIII, hoped to promote Christian unity, but knew there are different concepts about Mary among other Christians, especially Protestants. The council in its one mention of Mary as "Mediatrix", spoke of her as strengthening — not lessening — confidence in Christ as the one essential Mediator. The council, in speaking of Mary, used a biblical approach, with strong emphasis on her pilgrimage of faith. They also drew heavily from the Fathers of the Church, which Christians of all denominations respect.
