"Onecho" was originally the name of a pioneer post office operated by J.R. Wicks, who later became known as "The Father of Onecho".
Onecho Bible Church's roots go back over 130 years, to a group of Methodists that began meeting in 1876. Charter members of that church were the W.F. Hickmans and the Samuel Ensleys. Added shortly were the Henry Ensley s and others. A log school house at the foot of Cemetery Hill was the first place of gatherings, followed later by an unpainted, rough-board building known as "The Old Brown Schoolhouse".
In 1890, Mennonite families from Germany and Switzerland began attending the church along with the original Methodists. Among these families were the Rubins, Aeschlimans, Stevicks, Schlunegers, Nafzigers, Roulets, Allenbaughs and others. The Mennonites organized as a church group in 1893, meeting in a private homel.
They became the First Mennonite Church of Colfax, Washington, under the direction of the General Conference of Mennonites of North America field director On the same day, Paul R. Aeschliman was selected as pastor.
Rev. Aeschliman would preach his sermons in German, which were repeated afterwards in English. The Sunday School was carried on by the American Sunday School Union.
By 1895 it was becoming clear that a new church building was needed. Through the cooperation of the Methodists and Mennonites, a building was constructed on property donated by J.I. Tompkins. This site has been the Onecho church location ever since. The original structure was rebuilt in 1926.
The name "Onecho Bible Church" was adopted by vote of the congregation in 1964. An educational and administrative addition was constructed that same year. The present sanctuary was completed in 1981, and the Family Center was dedicated on July 4th 1998.
