Dear Fausto, I admire your interest for Latin. I know that you have studied it. It is correct to say "Ad maiora natus sum" (I was born for greater things!). This is used as a motto. If you want it in plural, it would be "Ad maiora nati sumus" ("we were born for greater things!). You may be confusing it with another one used by St.Ignatius of Loyola and by the Jesuits: "Ad maiorem Dei gloriam!" (For the greater glory of God!). Keep it up! Regards. Fr.Ivo da C.Souza
