Fair enough. So if the Bible says "a bishop must be the husband of one wife" and some person or organization tells me "a bishop must not be the husband of one wife", then I know that the latter is full of it.
I get your dig. There is another possibility, though... that you are wrong in your interpretation. As the Catholic Church understands the Apostolic Succession, St Paul was a Bishop in the Church. He was not married. He even went so far as to call that condition a blessing!
This passage of Scripture is not a command to be married, rather it is a prohibition against multiple marriages. The Church rightly understands it in a number of scenarios but one is interesting: the condition of a man whose wife dies. He may become a priest and then a bishop. He has had but one wife. However, if he were to remarry and then she also died, he would not now be a good candidate for the celibate life. Why? In his remarriage, he showed his commitment to that Sacrament and demonstrated his greater desire to not be celibate. It is a logical position.
