The Church of the Open Door was founded as an independent fundamental church in 1962 by Dr. Robert E. Mayer. For six months a Bible study was held in a private home. Regular Sunday and Wednesday services began in November of 1962. The small congregation met first in a rented storeroom on the corner of Fifth and Locust Streets. In November of 1963 the church was incorporated and moved into a larger church building on Fourth Street.
In the fall of 1978 Lebanon Christian Academy began. The church and school moved into a stone mansion located on East Walnut Street. In 1980 the church and school moved again, this time into a newly-constructed building at 875 Academy Drive where the church and school continue to thrive.
In the summer of 1997, Dr. Mayer resigned and in September of that same year, Rev. Craig L. Griffith, Sr. became Pastor of the church where he continues to serve the Lord faithfully.
In 2001 the church's name was officially changed to Open Door Baptist Church for the purpose of clarifying the church's doctrinal position to the community.
Burdened to further educate men and women in the truth of God's Word, Pastor Griffith established the Open Door Bible Institute. Classes began in the fall of 2003. This vision was expanded in 2013 when ODBC joined with other Pastors and Christian Leaders and established the Keystone School of Biblical Theology.
In the fall of 2016, ODBC became members of the Fellowship of Fundamental Bible Churches (FFBC).
Open Door Baptist Church continues to develop its ministries to further reach our community.
2016 marks the joyous celebration of 54 years of preaching the Word of God and reaching the Lebanon Area.
