- KI is a diverse community representing a broad constituency of nearly 1,000 families strong. KI has served the Philadelphia Jewish community with distinction since 1847. Our warm, caring communities in Elkins Park and Blue Bell offer many different worship opportunities, extensive educational opportunities for all ages, active social action and outreach programs and much more. KI offers a liberal interpretation of the Jewish tradition while remaining respectful of the tradition. We understand that every person and each family is unique in its needs and interests. We hope you will find KI to be your spiritual home.
