Eastbound, neither Jesus's celibacy nor priestly celibacy diminish the sanctity of marriage in any respect. Acts of celibacy and dedication to the service and love of God are acts of sacrifice which glorify God and create the opportunities for spirtual fatherhood or motherhood which are different from (but not necessarily better than) actual motherhood or fatherhood.
I, for one, am very glad that Jesus did not have any children. If he had, early Christians would probaby have been torn apart over the question of who were the heirs to his Kingdom, much like the Muslims, whose principal sects argue to this day over who are the proper authorities regarding his teachings--Muhammad's family or the caliphs?
As it stands, thankfully Christ left us no such tangled ambiguities. His legacy was directly bestowed on his Church and the apostles instead.
