Finanacial affairs always present, then and now, were present in 1868 when pew rentals were graded from $1.00 to $20.00, and brought in a revenue of $1,500.00. The Church Treasurer was given free pew rental while in office. In 1875 the financial concerns were at such a low ebb that the Society thought of leasing the church to the Presbyterians and returning to worship with them, but under the leadership of Rev. W.L. Bray, the church took on new life. A pipe organ was installed, as were stained glass windows and other improvements and by 1879 membership increased and financial problems abated. The First Congregational Church was destined to go forward.
It is significant that in 1877, though funds were scarce, a mission school was established in north Clinton. The Danish church was rented, and 82 persons enrolled in eight classes. George E. Jones (brother of Roys) was superintendent, with Josiah Russell assistant. This project was continued for a number of years with much success. As late as 1902 funds were appropriated for this purpose. It was during the pastorate of J.M. Hurlbert (1895-1899) that the office of Deaconess was added. Mrs. Roys Jones and Mrs. Elizabeth Scott were the first deaconesses to serve this church. The Boy's Brigade (the forerunner of Boy Scouts) was organized by Pastor F. B. Dean (1899-1905) in 1901, with John Goodwin as leader. Also in 1901, Hannah Goodwin and Helen Seaman were named the first women trustees.
With a forward look toward a need for a larger church, the old library building adjoining the church on the south was purchased in 1903 from John E. Mooney for $2,800. This later became known as Pilgrim Hall.
In 1918 and 1919 cottage prayer meetings were held, and union services conducted in the various churches to save light and fuel because of the war shortage.
In 1931, the National Council of Congregational Churches united with the General Convention of the Christian Church, to become the National Council of Congregational Christian Churches.
The first parsonage to be owned by the church, at 807 7th Ave. S., was purchased in 1941 and completely paid for in 1947. The parsonage was used as security for a $10,000 loan during he 1951 building of the Educational Building. This loan was paid in full in 1954.
Verne Spindell came to the church on 7th Ave. S. In 1945, plans for a new church building program were soon set up under his leadership. Mr. and Mrs. C.A. Depue made a gift to the church of 27 acres on the wooded hillside on 7th Ave. N. and Bluff Blvd. When the Building Chairman, H.D. Barnes, appraised the hillside site he remarked, "We could build a $10,000.00 church on that site, and it would look like a million." Also the bequest of $67,000.00 in memory of Bertha Anderson made by her husband helped to increase the building fund.
Due in great measure to the organizational ability of Mr. Spindell, the Educational Unit of the new church was brought to completion. The Sunday School unit and chapel, kitchen and dining room was built prior to Sanctuary. The cost of the building was pledged more than 90% before its dedication. The membership grew to 500.
