Be you a Christian, Buddhist, Muslim, Jew or Shinto, this time of year has been sacred to man since before any religion was founded. Huge bonfires lit the night to tempt the Sun back. To light your windows is assumed a Christian tradition. Yet many Christians do not observe this way. Here in America, we should all put at least a single light in the window at this time, if only to celebrate our unique heritage of toleration. Let us make it a tradition here in Jamaica Plain with the hope it spreads all across the nation: a light in every window for the unity of mankind.
