Well, Ake, most priests I know, live lives that would be very hard on family life. Many of them DO live lives that are totally dedicated to serving their congregations. My pastor had to borrow forty bucks from me on Sunday because he had given all his own money to the poor.
He once said from the pulpit, "If I don't have money to give to the poor, I get it from Joe Offer. I don't know if I've ever remembered to repay him." No, he hasn't repaid me, but I'm proud to help him in his charity - but if he had a wife and children, I'm not so sure that they'd be so happy.
Some priests accumulate a lot of money and live very comfortable lives, but many take their dedication very seriously. It's a hard way to live, but many of them do it very honorably.
