In St. Paul’s letter to Titus, he explains the caliper of people needed to evangelize.
”For this reason I left you in Crete so that you might set right what remains to be done and appoint presbyters in every town, as I directed you, on condition that a man be blameless, married only once, with believing children who are not accused of licentiousness or rebellious. For a bishop as God’s steward must be blameless, not arrogant, not irritable, not a drunkard, not aggressive, not greedy for sordid gain, but hospitable, a lover of goodness, temperate, just, holy, and self-controlled, holding fast to the true message as taught so that he will be able both to exhort with sound doctrine and to refute opponents.”
