When Our Lord wants a message to get out to His Church, he raises up a powerful Saint to do the task. Such a Saint was Gertrude the Great! She was the one to plant the seed which would bloom through the hands of another powerful Saint and visionary, St. Margaret Mary Alacoque, four centuries later, and subsequently through Saint Faustina Kowalska in the 20th Century, through the Mission of Divine Mercy. Our Lord's mandate to St. Gertrude was to herald devotion to His Most Sacred Heart.She came to us in the Thirteenth Century, a time of rampant heresy and glorious victory. The Lord promised that His Church, although besieged by persecution, would triumph in the end; in the Thirteenth Century, with His Infinite Humility, He raised up great Saints to bring this about. St. Gertrude received the title "the Great" partially because of the extraordinary gifts she received from the Lord, but we believe more for her total dedication to her Spouse Jesus.
