Yes, this book contains priest jokes and sister jokes and deacon jokes and bishop jokes and even one or two jokes that feature the Pope. But mostly these are jokes about lay people and the foibles of daily life from a Catholic (that is, Roman Catholic tradition) and a catholic (that is, universal and about everybody) perspective.
These jokes are clean and not mean and not intended to offend anyone. But if you can t laugh at yourself or the human condition, then you d be better off skipping this book. If, however, you think some of the stuff we humans do is funny, and if you admit that the Catholic Church is full of human beings, then perhaps The Book of Catholic Jokes is for you.
