Some churches are basically encounter sessions with a nice little speech given by the "let's get real/can we talk" pastor. They encourage people to engage in what amounts to public spiritual masturbation and call it "testimony".
Some people from groups like that mock how churches like mine have a very explicit, very deliberate, very same ritual week in, week out. The church year changes with the seasons, and the year A through D do readings through the entire Bible on the same themes. At the end of four years you've gone through most of it, always through the same structure of liturgy. If you go to a church like that long enough, you don't need the book of common prayer. Though you couldn't write out the entire Nicene Creed out if your life depended on it, once people start saying it, you don't need to read the words, they just flow.
It's a main reason why people hate changes to the rituals, and why people still say "and also with you" rather than "and with thy spirit".
There's another wisdom in doing this. Some days you can't pray. Some days you have nothing to offer God except your brokenness and your sorrow, your loneliness and your guilt. Some days you don't stand at the altar administering wine, or process with a candle, or sit in the pews, you sit in the balcony, unnoticed, keeping the uncontrollable crying inaudible and private.
Some days, you just show up. You just go through the motions. Because that's all you can do.
But every now and then, the words naturally come, on autopilot.
"Most merciful God,
we confess that we have sinned against theein thought, word, and deed,by what we have done,and by what we have left undone."
