The evening of Sept. 15 was a quiet Friday night for Rabbi Randy Fleisher, a leader of the Central Reform Congregation, the only synagogue within St. Louis city limits. Shabbat services were winding down, and two congregants were celebrating the one-year anniversary of their religious conversion with cake, hummus, cheese and crackers. But Central Reform was planning to stay open unusually late. And across the street, the lights of the First Unitarian Church of St. Louis stayed on too.
