Saint Ignatius of Loyola, founder of the Jesuits, was a mystic whose spiritual life centered on the Trinity, Jesus Christ, and the Eucharist. His spirituality is expressed in the Jesuit motto, Ad Majorem Dei Gloriam (“for the greater glory of God”). He is known for his greatest work, the Spiritual Exercises, which are grounded in the following themes: a sense of collaboration with God’s action in the world, spiritual discernment in decision making, generosity of response to God’s invitation, fraternity and companionship in service, and a disposition to find God in all things. Spiritual integration, also is a prominent theme of the Spiritual Exercises and involves integration of contemplation and action, prayer and service, and emotions and reason.
