In our service, near the middle, the celebrant will say "Let us now confess our sins against God and our neighbor". It never resonated with me; I could never focus on any personal "things done and left undone".
I ever imagined it was supposed tounload some really juicy, torturous, latent tidbit except I couldn't because nothing ever came to mind big enough to unload.
But I recently realised the confession doesn't have to be murder or some awful hidden secret -- in prayer I should just unburden yourself from the little things I beat myself up over. They are tiny, tiny things but they really weigh me down when I think about them. It can be as tiny as not handing back test grades in a timely manner or not staying in touch with the people important to me or not fully participating fully in organizations I belong to. Forgiveness for those things suddenly makes the church service more meaningful.
