In other words, God doesn't depend on our virtue to accomplish his purposes. Incidentally, the Catholic church also decreed that God's grace doesn't depend on your virtue either. Ex opere operantis assures lay people that they too can receive the grace of God even as sinners. God's grace doesn't depend on our virtue. We United Methodists have had our share of problems in this regard.
Sin is everywhere.
The Iowa Annual Conference has created policies about sexual misconduct for clergy and instituted strict rules about how ministers are to go about their business, apparently because we are worried about the damage to people from wayward clergy and of course about potential law suits. For instance, we are no longer to call on homes where a woman might be by herself. But I did get accused of misconduct in a divorce proceeding when an agitated husband remembered coming home one evening to find me talking to the pastor parish committee chair, who happened to be his wife. This caused no permanent damage, but it did bring home to me one of the dangers of the ministry. The fears of clergy misconduct are a sad reminder that sin is everywhere.
