Years ago, when I was a RE in the Colleyville, TX, PCA church, we had a Godly deacon who came under conviction that "husband of one wife" meant he had to be married, and was a lifelong bachelor, and nothing we could say dissuaded him. He resigned from the deaconate, and as I recall, he was one of our best ones. A year or so later, he died of a brain tumor. Bless his memory.
Since Paul had legal training, I don't know why he didn't say, "He must manage his own household well, with all dignity keeping his children, if any, submissive."
But years ago, I realized that the Holy Spirit has done a lot of things without checking with me on them.
