Peace Lutheran Church began as a mission congregation in November 1983, daughter of Lutheran Church of the Cross in Kent and granddaughter of Kings of Kings Lutheran Church in Renton. The Northwest District of the Lutheran Church-Missouri Synod had already purchased eight-plus acres on Kent-Kangley Road for the new mission church in 1981 and a house in the Timberlane community for a parsonage in early 1983, in which a newly hired Vicar would live while serving a year at Lutheran Church of the Cross.
In August Vicar Rod Flohr and his wife Beth arrived to help with the new mission church. Pastor Arnold Walta and Vicar Flohr took turns leading services at Timberlane Community Center and Covington Elementary School. In January 1984 the time came to name the new mission church and from 19 possible names submitted, Peace Lutheran Church was chosen in a close vote. In March 1984 the property was dedicated to the glory of God and when Vicar Flohr’s service time was completed in August, a Mission pastor was called, and Pastor Robert Kunz and his wife Ruth arrived from St. Joseph, Missouri in September.
In February 1985 the congregation rented a small log cabin church near Lake Sawyer for services and ministries and in June of the year Peace was recognized by the NW District LCMS as a chartered congregation of 32 families, 101 members including children.
