There is no basis in scripture for celibacy, in fact there is evidence to support that Jesus Christ was married as well as his 12 apostles, with the probable exception of John. The first several dozen popes were married and had children, and celibacy is not found within the Catholic faith until the 4th century, the very same time in which sexual abuse and misconduct against children began to take place in respect to written recorded history (it is unclear as to the actual starting point as records do not exist beyond this timeframe). Celibacy was developed and demanded due to finance, as married priests automatically passed down their wealth to their firstborn son, as was the customary practice of primogeniture, but if said priest had no heirs, their wealth went directly to the church
