For one evening in mid-April in New Castle, Pa., Temple Hadar Israel bustled with the sounds of prayers, the tinkling of glasses and dishes and even the joyful outbursts of a visiting toddler. About three dozen members and visitors had gathered on the first night of Passover over matzo ball soup and other traditional fare for a communal celebration of the ancient Jewish ritual meal. The chatter and laughter among the mostly older, informally dressed group provided a respite from the reality that the days of the historic synagogue in the Lawrence County city are likely numbered.
