Second Apostle of Germany

Today is the feast of St. Peter Canisius, Doctor of the Church. From a seventeenth-century translation of one of his catechisms (as slightly modernized by myself to make it easier to read):

What is the name and nature of the Cardinal Virtues?

Certain virtues are thus called Cardinal because they are as it were the fountains and hinges of all the rest, and as the door turns upon the hinges, so the whole course of honest life consists of them, and the whole frame of good works seems after a fashion to depend upon them. And they are accounted four in number: Prudence, Justice, Temperance, and Fortitude. Whereof it is thus written: She teaches Sobriety and Prudence and Justice and Virtue, than which things there is nothing in this life more profitable to men, where by Sobriety, Temperance, and Virtue, Fortitude, are not obscurely signified. And all of them are so commended unto us, that we may assuredly understand that by the eternal wisdom which is God they are properly bestowed, and are received and exercised with very great fruit of man's salvation. Which virtues are also called Officials, that is, appertaining to offices or duties, because from them, as Saint Ambrose has noted, spring the diverse kinds of offices; and are derived all manner of duties appertaining to the ordinary life of man, according to every man's vocation.
