You’d have to get scissors and cut stuff out of the bible before you could even get the idea that being married is better for all pastors.
Not all. But I’d say the large majority. Problem is so many that would HAVE made good pastors if they could have had a family aren’t there because of the celibacy requirement, so your candidate pool is made artificially small and full of liars (as they didn’t keep their vows, and I am certain many of them never intended to but took the vows anyway, being closeted homosexuals mainly).
