The Spiritual Exercises of St. Ignatius of Loyla is the core work of religious formation for members of the Society of Jesus, the single largest religious order within the Roman Catholic Church. For four and a half centuries in many thousands of editions in all languages, The Exercises have embodied fundamental spiritual principles essential to authentic Christian living.

The mystical insight informing Ignatius's own relationship with God--which he distilled in The Exercises--is that the divine love of God is providentially present in all the details of our existence. Here Ignatius shows how the faithful can be joined to God in all things, according to the Jesuit motto, Ad majorem Dei gloriam, "For the greater glory of God."
