Lord our God,
through Your loving favor,
You revealed to blessed Mechtild, your virgin, the hidden secrets of your providence. May we who know You now through faith rejoice hereafter to see You face to face.
Grant this through our Lord Jesus Christ, Your Son, who lives and reigns with you and the Holy Spirit, one God, for ever and ever.
A brief biography can be read here. One key point in the life of Saint Mechtild is that she was the dear friend of Saint Gertrude the Great and who had a spiritual daughter in the other Mechtild, that of Magdeburg, who lived at the same time.
