Liz Grossman writes about her brother's experience with church in Newsweek magazine. Her brother Tim has Asperger syndrome and obsessive-compulsive disorder with "savant characteristics of autism." From the article:

I had no idea what Tim did on those Sunday afternoons, but I knew that it filled him with a kind of peace no medication or doctor ever had. After church, he'd come over to our parents' house for family dinners with a sense of calm, his eyes settled, his body slightly less rigid. He even began making a habit, one of his thousands, of giving our mom a quick hug before he'd head home.
