To the greater glory of God.

The phrase expresses the idea that human actions—especially public, institutional, or creative works—should be oriented toward honoring God rather than personal prestige or worldly gain. In Catholic usage it functions as a dedicatory motto, framing achievements as ultimately subordinate to divine purpose. However, the wording is most famously associated with the Jesuit motto in Latin, “Ad maiorem Dei gloriam” (often abbreviated AMDG), and is widely used across Catholic contexts without being traceable to a single utterance by Pope Gregory XIII. As a result, it is better understood as a traditional devotional formula than a quotable line uniquely attributable to him.

Latin: "Ad maiorem Dei gloriam" (often abbreviated A.M.D.G.); English: "For the greater glory of God."
