Celibacy could prove a difficult issue for the Catholic Church,with a la carte Catholic priests in Africa,France and elsewhere keeping mistresses as housekeepers. In Ireland,it has contributed to the decline in the indigeneous clergy who are becoming an endangered species.
This should not be surprising.A couple of million years of human sexual evolution makes it extremely hard to repress sexuality. A psychologist's opinion I once read claimed that repressed sexuality will find an outlet somehow,sometimes in bizarre or even perverted activity.
On the other hand,recently I read a compliment of clergy by a non-Catholic English person that the strongest characters he had come across in life were Catholic priests and nuns. Could it be that the monumental struggle to repress sexuality strengthened their character?
Years ago I suggested to a Jesuit priest that the Church might change the celibacy rule,given that the rule didn't apply in the first few hundred years of the Church's existence and was only introduced on practical grounds, to prevent the families of the clergy from stealing Church property. The priest looked despairing and anguished when he said that his lifelong struggle with celibacy would be made look futile if celibacy was revoked.
