Mark Gruner

Fr Nicholas Nightingale Gruner (May 4, 1942 – April 29, 2015) was a Roman Catholic priest and a promoter of the message of Our Lady of Fátima, a recognized apparition of the Blessed Virgin Mary at Fátima, Portugal, in 1917. Father Gruner's interpretation of that message at times proved controversial, even among other groups of Traditionalist Catholics. In 1978, he founded the Fatima Crusaders (known today as The Fatima Center) and was its International Director.
