Monrovia Christian Church grew out of the Disciples of Christ groups of Morgan County. It was founded in 1874. A frame building was erected in 1872. Charter members were Ruth McCracken, Lucinda McCracken, S.G. McCracken, Joseph and Nancy Allison, Andrew and Ann Brown, William Dow, George Giles, Maggie Gosney, Stephen Hobson, Lizzie Hadley, James D. Hadley, Sarah Hadley, Jetha Lindley, William and Katharine Long, Zarilda Long, Alonzo and Minerva Lewallen, Sarah Lambert, C.A. and Theodocia Nelson, Susan Poe, Jesse and Nancy Reagan, Sarah and Tina Tuboton, Jemima Ruth, Mary Williams, Andrew Wilson, and Ruth Yeagar. The congregation later had disagreements that caused it to disband and, in 1881, reform as the Covenant of the Brethren and Sisters of Monrovia Christian Church. A brick structure replaced the old church in 1919 and was purchased by Monrovia Methodist Church in 1977.

     The current home of the Monrovia Christian Church is at the corner of Gordon and West Union Roads on land donated by the Claude Smith family. It was dedicated January 15, 1978.

Monrovia Methodist Church was organized around 1840 by Reverend Henry S. Dane. Earlier meetings were held, from around 1833, in the cabinet shop of William Cline. Some of the founding members were Edward Lindley, Walker Caveness, Isaac Johnson, William Mull, Joel C. McClellan, C. Marvin, D.C. Doan, James R. Williams, William Best, A.M. Dilley, J.K. Best, James Hudson, and L.B. Lewis. During a national split over the question of slavery in 1844 the name was changed to The Methodist Episcopal Church. In 1939 the separate branches of the Methodist Church reunited and in 1968, The Evangelical United Brethren merged with the Methodists to form the United Methodist Church.      On March 2, 1846, the deed for the property on Main Street was recorded. A frame church was built on the site around 1850 and still stands. It is currently an office building.

     The Old Monrovia Methodist Cemetery lies northwest of Terrace Drive behind a residence. Due East of the American Legion Post parking lot there is a path which leads to the site. The land was donated by Thomas Grisham to the church. Some graves are marked with field and creek stones. No Records are available for the first 40 years of the site's existence.

     The Nazarene Church is housed in a frame structure erected in 1885 by the Conservative Friends. It is located on Chestnut Street,( State Road 39), was purchased by the congregation in 1933 and remodeled in 1976. Charter members of the church were Ida Clark, Walter Griffith, Belle Goad, Sarah Goode, John Green, Philip Golay, and Fern Tuck.

     West Union Friends were organized in the late 1820s. Founding members included George Rubottom, William Johnson, Aaron Lindley, Jerry Hadley, William Allen, Ashley Johnson, Philip Johnson, Eli Townsend, Jesse Baldwin, Jonathan Doan Sr., Jonathan Doan, Charles Allen, Lot Hadley and Silas Gregory.

     The frame meeting house on State Road 42 was built in 1832. Until 1895 men and women were separated during business meeting due to the hesitance of women to speak in front of men. Lydia T. Painter wrote a description.

"The room was cut in two by a row of shutters through and through. The room on the East was always the Mens'; The one on the West was for Women Friends. The shutters were made to lower and raise on Monthly Meeting days. During silent worship the shutters were raised"

     The West Union Meeting started a school during the first meeting. Classes were held in the meeting house from 1832 and in 1834 a separate building was constructed. In 1859 West Union Friends School became Public School No. 9 and until 1898 it was supported by public funds. The meeting house was also an underground railroad station and pupils are reported to have seen escaped slaves waiting in the woods behind the buildings.

West Union Cemetery , in the churchyard on State Road 42, was first used in 1832 for the burial of Zimri Allen's wife and child. Among the more than 1500 graves are many local ancestors.
