Many definitions of the magis are proffered in Jesuit circles, not all of which are clear or helpful. The best definition, in terms of practicality, fidelity to the sources, and correspondence to other Ignatian themes, is “the more universal good.” It is closely linked to the unofficial motto of the Society of Jesus, “For the Greater Glory of God.”
