Methodists in Delta Township began meeting in a log schoolhouse in 1837 and, served by circuit riders, organized as a Methodist class in 1842 with two families. The class grew, and in 1865 the Reverend J. Gulic became its first appointed minister. On June 6, 1867, a Ladies Aid Society formed to raise funds for an adequate place of worship, and the church was completed in 1873. Designed and built in 1873 by Delta Township native Darius B. Moon, the original white frame church stood just northwest of the present church and was built with donated labor and much of the building material from members of the congregation. The 30'x 50' structure, which cost $340, served area Methodists for 110 years and, when completed, was a crisp, clean, simple rectangular building with a central entrance, rectangular windows, and a square louvered belfry topped with bracketed cornice and turned finial capping. The church was significantly enlarged in 1926 and 1954. During a special church conference in the summer of 1962, delegates from Delta Center and nearby Bethel and Millett voted to merge their three churches, and the first meeting of the newly formed church was held at Delta Center Methodist Church on June 24, 1962. The name Trinity Methodist Church was adopted on July 5, 1962. The last regular worship service in the frame church was held on March 10, 1968, and the congregation used the old church as a fellowship hall until it was razed on May 18, 1983.
