“You can be as leaven in the mass, those who are able to change even the great metropolises, the great cities, the great intellectual centers. You can bring a better future because within human realities everything is accomplished through the person, and it is the person who accomplishes it.
Of course if the person is carried by the power of God, in the grace of God, if he walks with Him, he or she is then capable of changing the world. Let the final word of this UNIV be this wish: that you better this world.” (John Paul II, Univ 1982)
