Am Yisrael Chai. Bring Them Home.

The day will come when the story of Israel in modern times will speak not just to Jews, but to all who believe in the power of the human spirit as it reaches out to God, as an everlasting symbol of the victory of life over death, hope over despair.
Rabbi Lord Jonathan Sacks, z"l

Making Lasting Connections 

Mosaic Law Congregation  // 








Shabbat, Holidays, Minyan

Our spirituality is lively, traditional, participatory, eclectic, and egalitarian. Wherever you are in your Jewish journey, your presence and participation are welcome.

Please share in our weekly Shabbat kiddush lunch and introduce yourself to our community. We look forward to meeting you.

Education Across the Generations

Teaching and learning across the spectrum are central to Jewish identity. We encourage participation in our many opportunities to learn together and to share your own teachings. We are proud of our Mercaz religious school and our extensive Adult Ed offerings, including our affiliation with the Melton School of Adult Jewish Learning.


We are particularly privileged to host two phenomenal libraries, the Central Valley Holocaust Educators' Network (CVHEN) and the Kashenberg, Ostrow, Hayward (KOH) Library and Cultural Center, whose extensive collections deepen our connection to our faith, people, history, and identity.   


Social Action, Cultural, Communal

Share in building a living, breathing, dynamic Judaism that values social interaction and tikkun olam, the betterment of the world.


We invite you to participate with us in shaping our community through Jewish activity and repairing the world one step at a time.
