NEW SQUARE, N.Y. — Last September, Aron Rottenberg did something radical.
Along with some friends, he began worshiping not at the grand synagogue at the center of this ultra-Orthodox Skver Hasidic community in Rockland County, but outside the village at a residence for the elderly.
Before long, a rabbinical court ruled that praying outside the synagogue was a serious violation of community rules.
Next, groups outside Mr. Rottenberg’s house smashed windows and dumped his daughter’s school desk and books on the front porch. And on May 22, an early-morning attack left Mr. Rottenberg with third-degree burns over most of his body.
Shaul Spitzer, 18, who lived in the house of Grand Rabbi David Twersky and worked as his butler, was charged with attempted murder and attempted arson.
