I'm not sure how other traditions handle it, but in the church of my childhood every service began with corporate confession.
"O almighty God, merciful Father, I, a poor miserable sinner, confess to Thee all my sins and iniquities with which I have offended Thee and justly deserved Thy punishment in time and in eternity..." (Lutheran Hymnal, Adelaide, 1973 edition)
Hey, talk about self-esteem!
In fact, I can still pretty-much recite those words off by heart from the liturgy that was pounded in Sunday by Sunday at St Matthew's in Hamilton. The current version has had a rewrite, but the substance remains unaltered.
Now along comes a dude who expresses all my misgivings in one lucid piece of writing. It probably won't make sense unless you have a background in this kind of liturgical tradition, but if you do, you might find yourself muttering an 'amen' or two along the way.
