Confession admits the particular sin. It is so hard that few will do it. This is common practice in civil law. The criminal is allowed to admit a misdemeanor rather than the felony he actually committed. Confession names sin.
Confession addresses the one who has been sinned against.
Send that fellow back down the aisle to the door of the man he injured. That is confession. A dozen times down the aisle would be easier, but not acceptable. Confessing to the church will not replace it. Send that other brother from the front seat to a secluded corner to pray.
