HISTORY OF THE CONGREGATIONAL CHURCH ON MERCER ISLAND

In 1963, the Washington North Idaho Conference, United Church of Christ, put in motion the steps towards realizing a new church on Mercer Island by allocating funds and seeking out a sponsoring committee. A sponsoring committee of fifteen Mercer Island residents was formed. The conference purchased a parcel of land on Island Crest Way for the future church. Permission was granted for early services to be held in Island Park Elementary School. In February 1964, the sponsoring committee called the Rev. Jim Gilliom as the first pastor of the Mercer Island United Church of Christ.

Over the years of the church’s history, membership has ranged from approximately 250 members to around 100 members.

Worship services were held at the Island Park Elementary school until the new church was completed in 1969. The new building was designed by Don Frothingham, a Seattle architect. The church building extensively uses Northwest materials and takes full advantage of natural lighting, bringing the trees and sky into the sanctuary. It was also designed so that the sanctuary could be used for a variety of events and the church makes its space available for rental to non-profit groups.
