"And what is true shalom, true peace? It is the sheleimut of the world, wholeness and redemption. It is the shelter of divine indwelling, the space within which we intuit the interconnected unity of God, nature, and person. People suffer in our home cities and in distant regions of the world. And though the pain of poverty and the scourge of injustice do not disappear with the lighting of the Sabbath candles, Shabbat does open up a vision of a world redeemed; we taste the dream of an earth blessed with perfection, an ideal that we can work toward again with renewed strength in the week to come. The wholeness and illumination of Shabbat call us to raise up the brokenness of this world and all who are driven low by its pain. Like the mitzvah to say the blessing over hallot that are whole, we are commanded to seek out the sparks that have been scattered and exiled — to make them whole again. The lehem mishneh is a reminder to us that Shabbat is a glimpse of a world restored and perfected, but it must also awaken us to the holy work of lifting up our fellow human beings from where they have fallen.
"For on Shabbat, the essence of shalom [peace]
is the aspect of sheleimut [wholeness and completion],
in the sense of the shelter of peace [sukkat shalom]
that is spread over us on the Sabbath."
