Check the scripture on what are the qualifications of a minister should be. One of the qualifications is that he must be a man of one wife. Ministers were meant to marry because he is a man, designed by God to have desires to reproduce. To reinforce this allowance for marriage, another qualification for ministers is that he must have good control and upbringing of his family. The Catholic belief that a married priest can not administer to his church is not accurate. Being head of a family and dealing with a spouse/children actually gives the minister insight that unmarried ministers do not have. It makes the minister more effective in understanding his church members of whom most will be married. Otherwise the Bible will explicitly forbid ministers to marry. I don't know what the historical theological reasoning the Catholic Church used to forbid marriage, but it runs in my opinion contrary to the Bible scriptures.
One of the qualifications is that he must be a man of one wife. I'm unaware of any Christian denomination that refuses to let single men serve as pastors, priests, or in any other clerical capacity.
The exegesis of that verse that you give is untenable. It would disqualify both Jesus and Paul from the ministry.
Ministers were meant to marry because he is a man, designed by God to have desires to reproduce.
You ought to take that up with Jesus, then. To whom was he referring when he spoke of those who were "eunuchs for the sake of the Kingdom of Heaven"?
