"The Apostolic Movement of  Schoenstatt is a Roman Catholic Marian Movement  founded in Germany in 1914 by Father Joseph Kentenich.  Fr. Kentenich saw the movement as being a means of spiritual renewal in the Catholic Church.  The Schoenstatt movement emphasizes a strong devotion to the Blessed Virgin Mary, upholding her as a perfect example of love and purity. It encourages its members to have the faith and purity of children, and to think of Mary as their mother."
