Celibate clergy are the exception worldwide rather than the rule, and treating them as the norm is a specifically Latin Catholic assumption.
Orthodox Christianity ordains married men to the priesthood, though a priest may not marry after ordination and bishops are drawn from the monastic clergy. Protestant traditions abolished the requirement at the Reformation as a matter of principle, and Luther's marriage to a former nun in 1525 was itself the argument in action. Eastern Catholic churches in communion with Rome retain married clergy.
Judaism has no celibate tradition at all and treats marriage and children as an obligation; rabbis marry, and the renunciant strand familiar from other traditions is largely absent. Islam likewise: Muhammad married, monasticism is explicitly discouraged in Muslim tradition, and the Sufi orders that produced most Islamic asceticism generally did not require celibacy of their members. Sikhism rejects renunciation deliberately and makes the householder life the religious ideal rather than a concession to weakness.
Within Buddhism the picture is mixed in a way that surprises people. Theravada monasticism is celibate, and disrobing is a normal and unshameful exit taken by a great many men who ordain temporarily. Japanese Buddhism is the significant exception: Jodo Shinshu clergy have married since Shinran in the thirteenth century, and the Meiji state legalised clerical marriage across all schools in 1872, after which it became standard, so that Japanese temple priesthood is now largely hereditary and passes from father to son. That is a real doctrinal and social divergence from mainland Buddhist practice, arrived at deliberately, and describing it as a lapse or a decline misstates what happened.
