and I am curious - ? Chap-verse ? for your assertion that "Jesus commends celibacy "for the kingdom.""
Matthew 19:12"For some are eunuchs because they were born that way; others were made that way by men; and others have renounced marriage because of the kingdom of heaven. The one who can accept this should accept it."
