Marian Devotions
A Marian devotion in Christianity is a gift (total or partial) of oneself, or one's activities to the Virgin Mary, i.e. a willingness and desire to dedicate oneself to, or venerate her, either in terms of prayers or in terms of a set of pious acts. Such prayers or acts may be accompanied by specific requests for Mary's intercession to God.
There are many Marian devotions, ranging from multi-day prayers such as Catholics' Novenas, the veneration of icons in Eastern Christianity, and activities which do not involve prayers, such as the wearing of scapulars or maintaining a Mary garden.
Devotion to the Virgin Mary does not, however, amount to worship - which is reserved for God; e.g. both Catholics and the Eastern Orthodox view Mary as subordinate to Christ, but uniquely so, in that she is seen as above all other creatures. In 787 the Second Council of Nicaea affirmed a three-level hierarchy of latria, hyperdulia and dulia that applies to God, the Virgin Mary and then to the other saints.
Marian devotions are important to the Roman Catholic, Orthodox and Anglican traditions, but most Protestant views on Mary do not accept them, because it is not documented in the Bible and they believe this devotion may distract attention from Christ. There is significant diversity of form and structure in Marian devotions practiced by different groups of Christians. Orthodox Marian devotions are well-defined and closely linked to liturgy, while Roman Catholic practices are wide-ranging and may include non-dogmatic beliefs such as the association of Marian devotions with predestination.
