Throwing in the whole family along with the qualifications....
1 This is a true saying, if a man desire the office of a bishop, he desireth a good work.
2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
3 Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;
4 One that ruleth well his own house, having his children in subjection with all gravity;
5 (For if a man know not how to rule his own house, how shall he take care of the church of God?)
6 Not a novice, lest being lifted up with pride he fall into the condemnation of the devil. - 1 Timothy 3
Do you think that one wife refers to polygamy or divorce?
