Calvary's Lighthouse was founded by Rev. Ruth Garlanger and registered by the State of Michigan as an Ecclesiastical Corporation on May 7, 1969.  The congregation first met at the YMCA in Benton Harbor for a short time, then at the city library.  Prior to beginning Calvary's Lighthouse, Reverend Garlanger was a pastor in the Church of God, Cleveland, Tennessee denomination for about fifteen years.  As it was from its beginning, Calvary's Lighthouse continues to be an independent, non-denominational, full-gospel church.

In 1971, church bonds were sold to members of the congregation and to the public and construction of the present church building was begun.  Construction proceeded slowly as

money became available through the sale of additional bonds and from gifts from various

individuals over the next few years.  The building was sufficiently completed for occupancy in 1974 and the first service was held in it.  In 1975 the building was completed inside and outside and the parking lot was constructed.  The parsonage was constructed in 1976 with generous help from members of the congregation.  In fact, most of the labor for the entire project was supplied by members of the congregation and friends on a donation basis.

Today, Calvary's Lighthouse Deliverance Center is a small yet diverse congregation of believers who are proclaiming the love of God to a lost and lonely world.
