If Aryeh Scheinberg were your typical Orthodox rabbi, the Jewish community of San Antonio would be engulfed right now in an ugly fight that would leave everyone a loser, most of all the children. But Scheinberg isn't typical, and the Jews of south Texas are at peace. Last August the community opened its spanking-new "campus," bringing the Jewish federation, family service, community center and San Antonio's sole Jewish day school under one $18 million roof. "It's an amazing place," says Pat Tonkin, who had become the day school's headmistress in July. "We're all in it together."
