Matzah symbolizes faith. In contrast to leavened bread, matzah is not enriched with oil, honey or other substances. It consists only of flour and water, and is not allowed to rise. Similarly, the only “ingredients” for faith are humility and submission to G‑d, which come from recognizing our “nothingness” when compared with the infinite wisdom of the Creator.
One of the holiday’s primary obligations is to eat matzah during the Seder. It is strongly recommended to use Shmurah Matzah to fulfill this commandment.
