Abdu'l-Baha invited the Baha'is of New York and New Jersey to join in a Unity Feast. He asked Wilhelm for the use of his West Englewood property, and issued the engraved invitations and played host. The food was prepared in New York City at the home of Carrie and Edward Kinney. True to 'Abdu'l-Baha's hopes, the 300 people assembled that day in 1912 exhibited the various hues and beliefs of humanity. Nearly a century later, about 1,000 adults and children comprise the Baha'i community in North Jersey.
Activities are many and varied.
Every 19 days Bahai's hold Feast, a spiritual, social, and administrative gathering. Many believers hold Firesides in their homes, where principles of the faith are shared and discussed. Today the Baha'i community in Bergen County considers the Wilhelm property in Teaneck its spiritual home. The original house still stands there, joined by a large log cabin built by Wilhelm in the 1920s. In this building classes are held for children and adults on Sundays.
