Catherine of Siena

 One day, while the virgin was praying in her little room, the Lord and Saviour of the human race appeared to her and announced what was to happen in these words, "Know sweetest daughter, that in the time to come your earthly pilgrimage will be distinguished by such marvelous new gifts from me that the hearts of ignorant carnal men will be amazed and incredulous..... But you must not be anxious or afraid, for I shall be always with you, and I shall free your soul from the evil tongues and the lips that utter lies.  Carry out undauntedly whatever the Spirit prompts you to do, for through you I shall snatch many souls from the jaws of hell and by my grace transport them to the kingdom of heaven."  The Life of St. Catherine of Siena.

The 25th child of a wool dyer in northern Italy, St. Catherine started having mystical experiences when she was only 6, seeing guardian angels as clearly as the people they protected. She became a Dominican tertiary when she was 16, and continued to have visions of Christ, Mary, and the saints. St. Catherine was one of the most brilliant theological minds of her day, although she never had any formal education. She persuaded the Pope to go back to Rome from Avignon, in 1377, and when she died she was endeavoring to heal the Great Western Schism. In 1375 Our Lord give her the Stigmata, which was visible only after her death. Her spiritual director was Blessed Raymond of Capua. St, Catherine's letters, and a treatise called "a dialogue" are considered among the most brilliant writings in the history of the Catholic Church. She died when she was only 33, and her body was found incorrupt in 1430.
