I could see that if a single minister later wished to marry, he ought to be expected to reaffirm his ministry before continuing on after the wedding. Just so that everybody is clear that the marriage is not supervening his idea of his responsibilities for the sake of the Lord.
Singlehood can help Protestant ministers, too, better concentrate on the calling of the Lord. I’ve seen it happen, where the wife passed away unexpectedly and the minister remained an unmarried widower.
There are virtues to being married and virtues to singlehood. There is no need to disparage either condition.
I'd have no problem with that at all.Regarding his dedication to the Lord's work the closest I've come to this is to see the dedication of married physicians to their patients.Being a physician,like being a priest,is a 24/7/365 calling and I know from personal experience (20 years working at a large hospital) that the married ones still get up at 3AM when a patient needs him/her and also works an 18 day when necessary.
