Often a non-Christian knows something about the earth, the heavens, and the other parts of the world, about the motions and orbits of the stars and even their sizes and distances... and this knowledge he holds with certainty from reason and experience. It is thus offensive and disgraceful for an unbeliever to hear a Christian talk nonsense about such things, claiming that what he is saying is based in Scripture. We should do all that we can to avoid such an embarrassing situation, which people see as ignorance in the Christian and laugh to scorn.
Saint AugustineHe 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.
Saint AugustineEven in waging war, cherish the spirit of peace-maker; that, by conquering those whom you attack, you may lead them back to the advantages of peace.
Saint AugustineI became evil for no reason. I had no motive for my wickedness except wickedness itself. It was foul, and I loved it. I loved the self-destruction, I loved my fall, not the object for which I had fallen but my fall itself. My depraved soul leaped down from your firmament to ruin. I was seeking not to gain anything by shameful means, but shame for its own sake.
Saint Augustine
