I don’t know if any other denomination holds confession like the Catholic church. A Google search could probably answer that, but it really doesn’t matter. I know it is a sacrament for Catholics to go to confession and confess their sins to the priest. We Protestants don’t do that because Jesus is our high priest and we can go straight and boldly to God the Father.
Having grown up in a non-confessional environment, I had no concept whatsoever of the healing nature of telling my “junk” to another person.
“Admitted to God, to ourselves, and to another person the exact nature of our wrongs.” – Step 5, page 59, Alcoholics Anonymous
That was a hard step for me. Granted Step 4 was hard enough writing all that crap down. But it was another matter to say it out loud to another person. Things that I had never ever EVER said out loud to ANYONE. Actually, there was only one thing that nobody else knew because I never told anyone. But now, both my sponsor and my therapist know about that. Since I’ve vomited all my secrets out (that I could remember up to that point), I don’t feel such a need to keep things hidden.
The saying, “You’re only as sick as your secrets,” is, at least for me, absolutely true. It was no wonder I turned to alcohol to numb. Of course, now I am dealing with the feelings from all that crap that I didn’t deal with at the time, so I am still pretty sick. But I’m getting better as I learn that feeling the anger and the hurt feelings is actually what emotionally healthy people do. They don’t stuff, suppress, and numb. They feel, work it out, let it go, and move on.
I wouldn’t dare suggest mandatory confession. For one thing, there is no way to enforce it that would even be remotely healthy. But I think within the context of a local church, confession to another person would be transforming because confession tears down facades, and confession frees us from darkness.
Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working. (James 5:16 ESV)
We don’t want to indiscriminately confess our junk because there are “tares among the wheat” inside and outside of church, and you need to be able to talk to someone you can trust is not going to harm you. You need someone who will pray with you and for you without judging you from self-righteousness, but yet will lovingly call you out when you need it. We all have blind spots. I think that is part of true confession to another person – being willing to have your blind spots pointed out to you, and admitting them for what they are. It won’t feel good, but it’s how we grow – by humbling ourselves.
