Everyone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.
You are surprised that the world is losing its grip? That the world is grown old? Don't hold onto the old man, the world; don't refuse to regain your youth in Christ, who says to you: 'The world is passing away; the world is losing its grip; the world is short of breath. Don't fear, your youth shall be renewed as an eagle.'
What is more insane than to be partakers of the Sacraments of the Lord and not partakers of the words of the Lord? These men truly have to say: "In Thy Name we have eaten and drunk," and they will have to hear: "I do not know you!" (Luke 13:26-27). They eat and drink His Body and Blood in the Sacrament and do not recognize in the Gospel His members spread over the whole world, and for this reason they are not numbered among them at the Judgment.
He who devoutly hears holy Mass will receive a great vigor to enable him to resist mortal sin, and there shall be pardoned to him all venial sins which he may have committed up to that hour.
For you [God] are infinite and never change. In you "today" never comes to an end: and yet our "today" does come to an end in you, because time, as well as everything else, exists in you. If it did not, it would have no means of passing. And since your years never come to an end, for you they are simply "today."
