"They must be innocent of wrongdoing, so that the wicked cannot besmirch God's church by claiming that those who lead and govern it are vile, disreputable rogues or men of evil life. Pastors must do their best to see that God's name is not blasphemed and that the wicked do not have cause to scorn the gospel and the church's good order. Pastors must do all they can to stop outsiders from speaking ill of them, and if they do, let there be no truth in what they say, and may their arrogance be rebuked." These are excerpts from John Calvin's sermons on First Timothy 3:7. I say yes and amen to what was quoted. Still, this is a hard thing. We were all converted from sinful lifestyles and we continue to sin as believers. I've sinned against unbelievers in my life since claiming Christ as my Saviour. And that even as they were aware of my profession of faith. It must appear downright hypocritical. What's the line that must not be crossed that would then disqualify a pastor or a laymen from the consideration of becoming a pastor?
