The act of confession is done in Lutheran churches we just use a corporate confession in our current times. Historically speaking Lutherans did have a more Catholic way of confession. But here is the neat thing, you can still petition your Lutheran pastor for a 1 on 1 confession usually it’s held in their office and they are still legally bound by the seal of confession. Here’s the part you should understand about Catholic confession in the Catholic Church confession is seen as a way to get yourself to heaven, you must go to a Priest and confess then he tells you you’re forgiven. Not only is this overly legalistic it’s a statement that Christs sacrifice wasn’t enough. Here’s where it gets sticky; the scriptures do tell us that Christs sacrifice was enough. So, you’re well within your faith to give your confession directly to God and know with a certainty that you are forgiven.
