Franciscan Media - Gertrude, a Benedictine nun in Helfta, Saxony, was one of the great mystics of the 13th century. Together with her friend and teacher Saint Mechtild, she practiced a spirituality called “nuptial mysticism,” that is, she came to see herself as the bride of Christ. Her spiritual life was a deeply personal union with Jesus and his Sacred Heart, leading her into the very life of the Trinity.
