We have. It is now only a question of what is just and right in the stewardship of God's church.
I think Scripture makes your path clear. You are to seek to restore this fellow to fellowship with the Lord. And it isn't going to take much effort on your part.
True. However, I would make this distinction: his sin was public because he broke the civil law. The community knows (because it made the news), the police know, grand jury members, judges, lawyers, IRS, insurance companies, inmates and others all know about it.
It makes no difference, and I would just caution you about speaking about the particulars. It might be construed by some as gossip.
His relationship to the world is not the priority relationship, his relationship with God is. Secondly, his relationship to the Body. He didn't need to sin to be despised by the world, his faith was enough for that. We don't concern ourselves with what the world thinks before we first concern ourselves with what God thinks, and what He has shown us as a pattern as well as given us explicit commandment in regards to a sinning brother.
Can you look back at the period in which the crime was taking place and determine if at any time you had sinned against God? Was that sin (and I am going to assume that at some point you did sin somewhere, lol, sorry, you can correct me if you were sinless during that period) inconsequential?
Here is what usually comes to mind when something like this comes up: I know that if I drop my guard I could end up in the same boat, and I thank God I haven't.
Satan is a crafty adversary, and works his wiles in the Body. When a member falls prey, we don't join the world in reviling him/her, we should do the very thing God has done for us. Not one of us can say "At least I am not as bad a sinner as that fellow," because our relationship with God doesn't start with sins, it starts from a relational perspective. God doesn't save on the basis of who sins less, who commits sins not worth mentioning, or that anyone merits salvation more than another. It's a matter of unmerited grace and mercy.
Paul wrote:
Philippians 2
King James Version (KJV)
1 If there be therefore any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any bowels and mercies,
2 Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind.
3 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
4 Look not every man on his own things, but every man also on the things of others.
5 Let this mind be in you, which was also in Christ Jesus:
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
Sometimes in our focus on the Incarnation...we forget that Paul makes a point here which is to have an application in our hearts.
The "mind of Christ" is to have a love for others that is sacrificial, and let's face it, there is no sacrifice in seeking to restore a brother.
God bless.
