The only reason I can see for the church not allowing married priests is MONEY AND the possibility of divorce. To have a help-mate is a great asset for a priest.
Those are not the reasons.
Most people do not know that although there were married priests up until the eleventh century, these men were not allowed to have sexual intercourse after ordination. There are papal and conciliar decrees dating from the beginning of the fourth century, which show that all clerics, whether or not they were married, were required to observe perfect continence after they were ordained and they were NEVER permitted to marry or remarry after ordination.
Celibacy marks the priest as someone consecrated to the service of Christ and His Church. It reflects the ontological change that has occurred in the priest as a result of his ordination. It configures the priest to Christ, the great High Priest, who never married and who called those who could do so to renounce marriage for the sake of the Kingdom. It also has an eschatological dimension, pointing to the coming of the Kingdom when marriage will no longer exist.
