From our earliest times, from our very beginnings, from the era of St. Ignatius and his first companions, the briefest summary of Jesuit spirituality has been "AD MAJOREM DEI GLORIAM" - a short Latin phrase that means "To the Greater Glory of God."
This phrase is what impells Jesuits to try their best in the service of the Kingdom of God: to help all men and women come to the knowledge of God's love for us in Christ, so that we all may respond to that love with "praise, reverence, and service of God our Lord."
The impelling word is "greater" -- a word that makes us always hope to do more, for God, for the Church, for the Lord's people, for the coming of God's Kingdom of justice, peace, and love.
