Following the logic of your argument, the bishop must have a wife and children too.

Those that do not have children cannot be bishop. Therefore bishops who cannot have children cannot be good bishops.

1 Tim 3:1 A faithful saying: if a man desire the office of a bishop, he desireth a good work. 2 It behoveth therefore a bishop to be blameless, the husband of one wife, sober, prudent, of good behaviour, chaste, given to hospitality, a teacher, 3 Not given to wine, no striker, but modest, not quarrelsome, not covetous, but 4 One that ruleth well his own house, having his CHILDREN in subjection with all chastity. 5 But if a man know not how to rule his own house, how shall he take care of the church of God?


2 "Of one wife"... The meaning is not that every bishop should have a wife (for St. Paul himself had none), but that no one should be admitted to the holy orders of bishop, priest, or deacon, who had been married more than once.
