Then explain away 1 Timothy 3:4 where it says the have had to prove themselves capable by managing a household and children prior to being considered for leadership positions.
The verse also says a bishop must have his children under submission. So you are saying someone must be married AND must have children to be considered to be a bishop? Someone married but without children cannot be a bishop?
So in your opinion, Paul was saying that he himself was not qualified to be a bishop?
