In the Torah, only the priests of the Temple are commanded to wash, and only before they partake of the sacrificial meal. Today, we have no Temple in Jerusalem, no altar, no priests and no sacrifices. Instead, every home can be a Temple, every table an altar, every meal a sanctified experience, and every Jew a priest. And eating, a mechanical biological function, can be transformed into a ritual filled with meaning.
