- Congregation Kahal Kadosh Beth Elohim provides opportunities for practicing Reform Judaism in an atmosphere of serenity, warmth, mutual acceptance, and historical significance. Established in 1749, Congregation K.K. Beth Elohim became the first Reform Jewish congregation in the United States in 1841. We recently celebrated the sesquicentennial of our majestic synagogue, the oldest surviving Reform synagogue in the world. We are more than just a house of worship; we are a vibrant and caring congregational family. The best way to learn about us is to visit us in person. We cordially invite you to attend our Shabbat services and any of our other functions and activities. Share with us the friendly atmosphere that is "The Temple."
