- The Boston Synagogue is the only synagogue located in the heart of downtown with 52 week Shabbat and Holiday services. Our mission is to serve the needs of the diverse body of Jews living in downtown Boston. We are unaffiliated â€“ and the synagogue is trans-denominational egalitarian, where both women and men are active participants in the service. There is an openness to all and itâ€™s a place where people across Jewish denominations can make their own spiritual connections. We welcome you wherever you might be on your Jewish journey.
