The Zion Congregational Church of Treynor, Iowa binds together followers of Jesus Christ for the purpose of sharing in the worship of God, and in the making of his will dominant in the lives of persons, individually and collectively, especially as that will is set forth in the life, teachings, death and resurrection of Jesus Christ.

In 1901, the Free Evangelical Lutheran Zion Congregational Church of Treynor was founded with only thirty-eight members. Four acres of land was donated for the construction of a church, and with the help of Rev. Mr. Osthoff, what is known today as the Zion Congregational Church was organized. The church was built on a foundation of believing in the sacred right of the individual to worship the Lord God as revealed in His Holy Word and inspired by the Holy Spirit to the dictates of his heart. Today, the congregation builds upon the same principals on which it was created, and continues to provide Christian outreach and maintain a vital presence in the Treynor Community.
