Blessed George Matulaitis (†1927) was a Roman Catholic Bishop of Vilnius from 1918 to 1925 and founder of the Sisters of the Immaculate Conception of the Blessed Virgin Mary. Dubbed the "Marian Renovator," the Lithuanian-born Blessed George was the priest who envisioned religious working together with the laity for the good of the Church. The principles he wrote about are defining points of the Association of Marian Helpers. He was beatified on 28 June 1987, by Pope John Paul II.
