The logic of man vs. the logic of God...
IF the Bishop's wife and children die, the Bishop still has the life experience of a family...That's the point Paul makes...You can not minister to families if you've never had a family of your own, AND, you must show that you were successful at having a family...
Clearly, the point of Pauls requirement that a bishop be "the husband of one wife" is not that he must have one wife, but that he must have only one wife. Expressed conversely, Paul is saying that a bishop must not have unruly or undisciplined children (not that he must have children who are well behaved), and must not be married more than once (not that he must be married).
NO...The point of God's requirement is just exactly what it says...If God wanted it to say what you claim it means, God would have written it that way...
For one, if "the husband of one wife" really meant that a bishop had to be married, then by the same logic "keeping his children submissive and respectful in every way" would mean that he had to have children. Childless husbands (or even fathers of only one child, since Paul uses the plural) would not qualify.
In fact, following this style of interpretation to its final absurdity, since Paul speaks of bishops meeting these requirements (not of their having met them, or of candidates for bishop meeting them), it would even follow that an ordained bishop whose wife or children died would become unqualified for ministry!
The theory that Church leaders must be married also contradicts the obvious fact that Paul himself, an eminent Church leader, was single and happy to be so. Unless Paul was a hypocrite, he could hardly have imposed a requirement on bishops which he did not himself meet. Consider, too, the implications regarding Pauls positive attitude toward celibacy in 1 Corinthians 7: the married have worldly anxieties and divided interests, yet only they are qualified to be bishops; whereas the unmarried have single-minded devotion to the Lord, yet are barred from ministry!
