St Augustine on anger

"... And well do you know, my excellent brother, how, in the midst of such offenses, we must watch lest hatred of any one gain a hold upon the heart, and so not only hinder us from praying to God with the door of our chamber closed, but also shut the door against God Himself; for hatred of another insidiously creeps upon us, while no one who is angry considers his anger to be unjust. For anger habitually cherished against any one becomes hatred, since the sweetness which is mingled with what appears to be righteous anger makes us detain it longer than we ought in the vessel, until the whole is soured, and the vessel itself is spoiled. Wherefore it is much better for us to forbear from anger, even when one has given us just occasion for it, than, beginning with what seems just anger against any one, to fall, through this occult tendency of passion, into hating him. We are wont to say that, in entertaining strangers, it is much better to bear the inconvenience of receiving a bad man than to run the risk of having a good man shut out, through our caution lest any bad man be admitted; but in the passions of the soul the opposite rule holds true. For it is incomparably more for our soul's welfare to shut the recesses of the heart against anger, even when it knocks with a just claim for admission, than to admit that which it will be most difficult to expel, and which will rapidly grow from a mere sapling to a strong tree. Anger dares to increase with boldness more suddenly than men suppose, for it does not blush in the dark, when the sun has gone down upon it..."

Letter to Profuturus

Virtue: a means, not an end - Fr Faber

"Virtue itself is a means, not an end; for virtue is not God, nor union with God. Do not think this admonition strange. It is one that was constantly in the mouth of St. Francis of Sales. We are so bad that we can make even our pursuit of virtue a hindrance to our love of God."

Useless knowledge - Thomas a Kempis

"Shun too great a desire for knowledge, for in it there is much fretting and delusion. Intellectuals like to appear learned and to be called wise. Yet there are many things the knowledge of which does little or no good to the soul, and he who concerns himself about other things than those which lead to salvation is very unwise."

Dressing appropriately - St John Baptiste de La Salle

If you wish to be dressed appropriately, follow the customs of the country, and dress more or less like people of your rank and age. Still, it is important to take care that your clothes have nothing luxurious or anything superfluous about them. You must avoid whatever suggests ostentation or worldliness.

The best way to judge the appropriateness of clothing is by custom; follow it without fail. Because the human spirit is prone to change and the things that pleased us yesterday no longer do so today, there have been invented, and are still being invented every day, all sorts of different ways of dressing to satisfy this changing spirit. Those who would want to dress as people did 30 years ago would make themselves look ridiculous and eccentric. It is, however, characteristic of the conduct of people of good judgment never to attract attention to themselves in any way.

Fashion is what people call the style in which clothes are made at a given time.You ought to follow it in the matter of your hats, linen, and outer garments. It would be against decorum for you to wear a tall hat or one with a wide brim when everyone else uses low-cut hats with narrow brims. Nevertheless, it is not always advisable to adopt all the newest fashions right away. Some of them are capricious and bizarre, while some are reasonable and conformable to decorum. Just as you ought not to go against the latter, neither must you adopt too hastily the former, which ordinarily are followed only by a few people and do not last very long.

The surest and most reasonable rule concerning fashion is do not invent your own, do not be the first to try it, and do not wait until everyone else has given it up before abandoning it.

 Rules of Christian Decorum and Civility

Needless contradiction - St Francis de Sales

"It was a saying of S. Louis, that one should contradict nobody, unless there was sin or harm in consenting; and that in order to avoid contention and dispute. At any rate, when it is necessary to contradict anybody, or to assert one’s own opinion, it should be done gently and considerately, without irritation or vehemence. Indeed, we gain nothing by sharpness or petulance."
