The Free Spring Church is part of the denomination called the Church of the Brethren which began in 1708 in Germany when Alexander Mack and seven others experienced believers' baptism through trine immersion.
After the Brethren immigrated to Pennsylvania, the Lost Creek Congregation was established near McAlisterville. By the time of the Civil War, a large number of Lost Creek members were living in the Van Wert area, so it was decided to erect another meeting house there. Northwest of the village of Van Wert there were numerous springs, and especially one of dependable strength, flowing when others had receded. Passersby could take of its water "freely." Gradually it came to be known as "Free Spring." Predictably, the new meeting house became known as "Free Spring Church of the Brethren."
