I Timothy 3:2, what does it say? Well it says that a bishop must be blameless, the husband of one wife, etc. If we want to take a hard line on that, then we could disqualify every preacher that ever lived. First, how does one define blameless? Does Paul mean we must be perfect, totally devoid of sin. Obviously not, for then only Jesus Christ would be qualified. No, it must mean with respect to men. In other words, one must be living his life in a biblically sound manner, striving to the best of his ability to keep the commandments of God. What does the "husband of one wife" mean? Does it mean one must be a husband? If so then you have disqualified Jesus Christ, Paul, and many, many others. Obviously that wasn't Paul's intent. What about widowers? It isn't as commonplace now, but in the old days it was fairly common that a preacher's wife would die young and he would remarry. Obviously, this couldn't have been what Paul meant. I think it's obvious Paul is writing this in order to dissuade having more than one wife at a time.
Note John Gill's commentary here: "only if he marries or is married, that he should have but one wife at a time; so that this rule excludes all such persons from being elders, or pastors, or overseers of churches, that were "polygamists"; who had more wives than one at a time, or had divorced their wives, and not for adultery, and had married others"
Gill then goes on to point out that polygamy and divorce was rampant among the Jews (and though he doesn't say this, probably among the gentiles as well). It seems that Paul is writing this to disqualify polygamists and men who just divorced their wives for no good reason and married another.
So, here's a guy who obeyed God's call into the ministry. He did his best to faithfully carry out his charge. However, his wife threatened to divorce him if he didn't give up the ministry. What is one to do? According to some he should have left what God called him into just to appease his wife. Folks, doesn't it sound like Satan is attacking a man of God here? Never should a man choose his wife over God. A man should love his wife as Christ loved the church, but not exalt her over God. If he did all he could save leaving the ministry to save his marriage and she still divorced him, I fail to see how he is disqualified. Sounds to me like he is loving God more than son or daughter, and father or mother.
