The Rev. Father John Croiset, S.J., was a French Jesuit priest and author of the seventeenth and eighteenth centuries. After serving as St. Margaret Mary's spiritual director from 1647-1690, he was able to write his The Devotion to the Sacred Heart as intimately familiar with our Lord's particular revelations to the saint. Father Croiset's work was originally published by The Radio Replies Press Society, Minnesota, and received the Nihil Obstat and Imprimatur circa 1959. It was also copyrighted by TAN in 1988.
