We blaspheme: 1. When we say that God is not just in making some people so rich that they have everything in abundance while so many others are so wretched that they have difficulty in getting bread to eat. 2. When we say that He is not as good as people say, since He allows so many people to remain weak and despised by others while there are some who are loved and respected by everyone. 3. Or if we say that God does not see everything, that He does not know what is going on in the world. 4. If we say: "If God shows mercy to So-and-So, He is not just because that man has done too much harm." 5. Or again, when we come up against some loss or setback and we lose our temper with God and say such things as: "Ah, but I certainly have bad luck! God cannot do any more to me! I believe that He does not even know I am in the world, or if He does know, it is only so that He can make me suffer!" It is also blasphemy to criticize the Blessed Virgin and the Saints by saying such things as: "That one has not much power! I don't know how many prayers I have said to him (or her), and I have never got anything."
