52 A true knowledge of the real difficulties of celibacy is very useful, even necessary, for the priest, so that he may be fully aware of what his celibacy requires in order to be genuine and beneficial. But with equal fidelity to the truth, these difficulties must not be given greater value or weight than they actually have in the human or religious sphere, or be declared impossible of solution.
