6 An elder must be blameless, the husband of but one wife, a man whose children believe and are not open to the charge of being wild and disobedient. 7 Since an overseer is entrusted with God’s work, he must be blameless—not overbearing, not quick-tempered, not given to drunkenness, not violent, not pursuing dishonest gain. 8 Rather he must be hospitable, one who loves what is good, who is self-controlled, upright, holy and disciplined. 9 He must hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and refute those who oppose it.
Note that Paul's list of positive traits in verse 8 starts with hospitable. Verse 9 has the elder fighting for the faith and refuting bad doctrine, but he's supposed to disagree in an agreeable manner. Self controlled and disciplined are also virtues of an elder.
That runs counter to the in-your-face prophet mode many preachers and bloggers get in to, where the more inhospitable they are to their foes, the better. A steady diet of brimstone-slinging scares more folks off than it converts.
