Smith writes from a protestant perspective, so certain chapters, though very funny, are not directly applicable to us Catholics, e.g. "Selecting the Clerical Wife." "The most important one piece of equipment the aspiring clergyman will acquire."
Other sections are either directly or closely applicable to the Catholic ministry, such as Smith's advice on "pastoral counseling," "the theology of church finance," developing a preaching program, good and bad hymns, dealing with the committee structure of a parish, the differences between managing mens' and womens' organizations, religious education, wedding rehearsals, and achieving the crucial "humility/ability balance."
Here's a sample, from the section on learning the professional stance of the clergyman:
Perhaps the best single word to describe the flavor of personality, one must strive to achieve is “pious.” This implies that the preacher will gather up, in himself, a host of qualities and characteristics and distill them into an essence which he exudes at all times, and which advertises, unmistakably, that here is a man of much prayer, meditation and lofty thoughts; a man who has disentangled himself from the secular, soiling concerns which obsess most men — in short, a clergyman.
Now someone is bound to say that this means a preacher, to be a success, must be religious — a contention which this book is written to deny. Here, we must pause to make a distinction between “religious” and “pious.”
A genuinely-religious man is, as the sociologists would say, inner-directed. He has deep and abiding convictions, usually derived from his faith in God and what he believes to be God's will. Thus, he is likely to be socially-irresponsible, largely uninterested in the kind of impression he makes on people, often involved in unpopular causes. He tends to be a crusader, frequently intolerant of what he conceives to be injustice or evil. Unfortunately, he is usually tactless, making enemies unneccessarily and, thus, becoming an embarrassment to the church.
