St. Paul and Jesus Christ Himself say celibacy is better. That should put to rest the fact that it is dangerous as does centuries of tradition. However, both also say that those who won’t choose it should marry, lest they be burnt.
No one is forced to choose celibacy as no one is forced to become a priest. The problem is those who are seeking and are accepted into the priesthood who don’t want to live continent–its no different than a man who marries one woman, but intends to still be promiscuous. Does the fact that such men exist make marriage dangerous? Such a man should not have been allowed to marry. In fact, 50% of marriages end in divorce–again, do those who fail to live up to their vows invalidate the good of the thing they have transgressed? Should we abolish monogamous marriage? Of course not.
Those who will not embrace continence should not be ordained. Those who violate their promises do not negate the good of those promises
A book that came out a while back called “Goodbye, Good Men” gave an explanation for why so many were ordained who shouldn’t have been (and others turned away who shouldn’t have been). There was also a false idea after Vatican II that celibacy was going to be abolished in the near future and the discipline was taken less seriously for a time. I believe things improved since then, but there is still work to be done.
At the end of the day, there will always be sinners in the Church, including the clergy. Many are called, but few are chosen, as Jesus says.
