I experienced my first Jewish Renewal Yom Kippur at the old Elat Chayyim in Accord, New York ten years ago. One of the practices which moved me most was a practice of collaboratively writing our own Al Chet prayer.
The Al Chet prayer -- "For the Sins (Which We Have Sinned Against You By....)" -- is a laundry list of places where we have missed the mark in the last year. That year at Elat Chayyim, before the holiday began, we each wrote down the places where we felt we'd missed the mark in the previous year. Then the index cards containing our words were mixed up and re-distributed. When it came time for the Al Chet prayer, we sang each others' words. The intimacy of that experience moved me deeply.
For the last several years, we've adapted this practice at my shul. At Selichot services on the Saturday evening before Rosh Hashanah I play quiet guitar music while people write down places where they've missed the mark, things they feel they need to release in order to reach forgiveness on Yom Kippur. Some of our Hebrew school kids engage in this same practice during Hebrew school. Then I collect the basket of cards and type up what's in it, and that becomes the Al Chet which our student hazzan and I chant on Yom Kippur morning.
For those who are interested, here's my community's Al Chet for this year. I share it in hopes that it might speak to you, too, and might help this prayer come alive for you in a new way.
(And if you're going to be at CBI on Saturday morning, you might consider not reading any further, so that these words can reach you fresh when we sing them from the bimah...)
