- The United Christian Church of Marietta was built around 1900, when women in the community formed a Women's Aid Society to build a church in Marietta. There were 21 charter members of the society--all women, because the men said they were too busy tending to their own work.The Society bought property from Eugene Baker for $50. After a few years, a church was built by the Wright brothers of Marcellus at a cost of $700.
- The bell that still rings each Sunday morning was donated by Mr. and Mrs. George Case.
- The pews and large chandelier were given by the Presbyterian Church of Marcellus.
- The pulpit Bible was sent to the church by the Rev. Joshua Meade of Newark, NJ.
- The Rev. William M. Case became the first regular pastor.
- In April 1951 the name of the church was changed from the Women's Aid Society to the United Christian Church of Marietta.
- In 2009 land was purchased behind the church for new Church Expansion. Completed in 2011
