There's the option of allowing priests to marry, but require that their children be grown.
"There's the option of allowing priests to marry, but require that their children be grown."
Good idea. Actually, the Apostle Paul suggests just such a system both in his letters to Timothy and to Titus.
Those scriptures say that elders (also translated "pastors," "overseers," or "bishops") of the church are to be of impeccible character. They are to have only one wife and children who are old enough to be believers and who respect and obey him "for if anyone does not know how to manage his own family, how can he take care of God's church?"
Young men may be spiritually zealous, but it sounds to me like church leadership was meant for the spiritually mature.
Some things just take time and experience.
