Dulia (Latin) in the context of "Holiness"

The veneration of Mary in the Catholic Church encompasses various devotions which include prayer, pious acts, visual arts, poetry, and music devoted to her. Popes have encouraged it, while also taking steps to reform some manifestations of it. The Holy See has insisted on the importance of distinguishing "true from false devotion, and authentic doctrine from its deformations by excess or defect". There are significantly more titles, feasts, and venerative Marian practices among Roman Catholics than in other Western Christian traditions. The term hyperdulia indicates the special veneration due to Mary, greater than the ordinary dulia for other saints, but utterly unlike the latria due only to God.

Belief in the incarnation of God the Son through Mary is the basis for calling her the Mother of God, which was declared a dogma at the Council of Ephesus in 431. At the Second Vatican Council and in Pope John Paul II's encyclical Redemptoris mater, she is spoken of also as Mother of the Church.
