Another Fundamentalist argument, related to the last, is that marriage is mandatory for Church leaders. For Paul says a bishop must be “the husband of one wife,” and “must manage his own household well, keeping his children submissive and respectful in every way; for if a man does not know how to manage his own household, how can he care for God’s Church?” (1 Tim. 3:2, 4–5). This means, they argue, that only a man who has demonstrably looked after a family is fit to care for God’s Church; an unmarried man, it is implied, is somehow untried or unproven.
This interpretation leads to obvious absurdities. 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! Clearly such excessive literalism must be rejected.
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 Paul’s 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!
The suggestion that the unmarried man is somehow untried or unproven is equally absurd. Each vocation has its own proper challenges: the celibate man must exercise “self-control” (1 Cor. 7:9); the husband must love and care for his wife selflessly (Eph. 5:25); and the father must raise his children well (1 Tim. 3:4). Every man must meet Paul’s standard of “managing his household well,” even if his “household” is only himself. If anything, the chaste celibate man meets a higher standard than the respectable family man.
Clearly, the point of Paul’s 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).
The truth is, it is precisely those who are uniquely “concerned about the affairs of the Lord” (1 Cor. 7:32), those to whom it has been given to “renounce marriage for the sake of the kingdom” (Matt. 19:12), who are ideally suited to follow in the footsteps of those who have “left everything” to follow Christ (cf. Matt. 19:27)—the calling of the clergy and consecrated religious (i.e., monks and nuns).
Thus Paul warned Timothy, a young bishop, that those called to be “soldiers” of Christ must avoid “civilian pursuits”: “Share in suffering as a good soldier of Christ Jesus. No soldier on service gets entangled in civilian pursuits, since his aim is to satisfy the one who enlisted him” (2 Tim. 2:3–4). In light of Paul’s remarks in 1 Corinthians 7 about the advantages of celibacy, marriage and family clearly stand out in connection with these “civilian pursuits.”
An example of ministerial celibacy can also be seen in the Old Testament. The prophet Jeremiah, as part of his prophetic ministry, was forbidden to take a wife: “The word of the Lord came to me: ‘You shall not take a wife, nor shall you have sons or daughters in this place’” (Jer. 16:1–2). Of course, this is different from Catholic priestly celibacy, which is not divinely ordained; yet the divine precedent still supports the legitimacy of the human institution.
