“A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;”
King James Version (KJV)
3:2 Therefore - That he may be capable of it. A bishop - Or pastor of a congregation. Must be blameless - Without fault or just suspicion. The husband of one wife - This neither means that a bishop must be married, nor that he may not marry a second wife; which it is just as lawful for him to do as to marry a first, and may in some cases be his bounden duty. But whereas polygamy and divorce on slight occasions were common both among the Jews and heathens, it teaches us that ministers, of all others, ought to stand clear of those sins. Vigilant, prudent - Lively and zealous, yet calm and wise. Of good behaviour - Naturally flowing from that vigilance and prudence.
1Ti 3:2 A bishop then must be . . . . None must be appointed because they desire the place. None are eligible unless they fill the following qualifications. Blameless. Not under charges; of good repute. The husband of one wife. A married man, and having only one wife. In those loose times of divorce, men might be converted who had successively several wives. Divorce for unscriptural reasons would not free a man from his first, lawful wife. Hence the limitation to those who had only one living wife. I do not think there is any reference to re-marriage after the death of a wife. Sober minded. Sedate. Given to hospitality. Often saints by persecution were made homeless. The bishops must set the example of receiving such. Apt to teach. Men who have the knowledge and discretion which fit them to teach the flock.
