A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; (1 Tim. 3:2)
If he is as above, why not? What if his wife divorced him because he chose Christ and she did not? (this happened to me) And, he never remarried(also my situation), holding to the Lord's teaching regarding committing adultery in such an instance. Is she not still the wife of his youth and the only wife he's ever had?
As to being blameless(living a holy life unto the Lord), it is mandatory for all saints (not just the pastors) to put off the life of sin and live in righteousness, holiness and obedience.
"Is a divorced man permitted to be a pastor in your current denomination? Is so, why? If not, why?"
MAKE THAT INSTEAD: Is a divorce AND remarried man permitted to be a pastor in your current denomination? If so, why? If not, why?
