The Feast of St Gertrude the Great, V, IIIrd Class
Today is the Feast of St Gertrude the Great. A Benedictine of the XIIIth Century, she was an early apostle of that Devotion which St Margaret Mary would bring to the world, that to the Sacred Heart.
The Collect from the Roman Breviary:
O God, who in the heart of thy blessed Virgin Gertrude didst prepare a mansion acceptable unto thyself : we beseech thee, by her merits and intercession, mercifully to cleanse our hearts from all defilements ; and to vouchsafe unto us to rejoice in her perpetual fellowship in heaven. Through.

In a vision she was given the Prayer which Our Lord told her would release 1000 Souls from Purgatory every time it is said with love and devotion. "Eternal Father, I offer You the Most Precious Blood of Thy Divine Son, Jesus Christ, in union with the Masses said throughout the world today, for all the Holy Souls in Purgatory, for sinners everywhere, those in the Universal Church, in my home, and in my family."
The article on her from the Catholic Encyclopædia.
From the Mission To Empty Purgatory, a site dedicated to promotion of her prayer.
