Some have paid me an undeserved compliment by supposing that my Letters were the ripe fruit of many years' study in moral and ascetic theology. They forgot that there is an equally reliable, though less creditable, way of learning how temptation works.

Besides reasoning about matters of fact, men also make moral judgements.

It is when we notice the dirt that God is most present in us; it is the very sign of His presence.

and a charge of lying against someone whom you have always found truthful is a very serious thing; a very serious thing indeed.

Our souls demand Purgatory, don't they? Would it not break the heart if God said to us, It is true, my son, that your breath smells and your rags drip with mud and slime, but we are charitable here and no one will upbraid you with these things, nor draw away from you. Enter into joy? Should we not reply, With submission, sir, and if there is no objection, I'd rather be cleansed first. It may hurt, you know-even so, sir.

Do not let us mistake necessary evils for good.

Our merriment must be of that kind (and it is, in fact, the merriest kind) which exists between people who have, from the outset, taken each other seriously - no flippancy, no superiority, no presumption. And our charity must be a real and costly love, with deep feeling for the sins in spite of which we love the sinner - no mere tolerance or indulgence which parodies love as flippancy parodies merriment.
