Matthew 18:15 tells us: "Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother."
How do you go to a big-name preacher who got into a scandal, destroyed your church, or destroyed several families, and talk to him privately? Even the context deals with a local Christian who is in your same church as being the problem.
God's commands aren't burdensome, so here's the solution. Chose to forgive the person, and then choose to have a different attitude. I am on the pastors son's long list of victims. But while I worked for him, I was able to teach a large teen-age Sunday school class and teach Bible lessons in the church youth center. I took the attitude that he had been working for me: he had organized a successful youth ministry, and that youth ministry had helped me succeed. He sinned against a lot of people, but he didn't sin against me.
Are you feeling pain because someone wronged you? Choose to forgive him, and then choose to have a different attitude. Remember that all things work together for good to them that love the Lord, look at the benefits you received, and move on.
