Traveling on foot, with his gun and retriever, Phylax, Pastor Weyel visited many Chicago area places. On his journeys he found Lutheran families in Frankfort township and decided to help them organize a congregation. In May 1850, he moved to the Hickory Creek settlement and began serving these families.

Several Swiss & Palatinate families with Reformed Church background joined with the Lutheran families at first, but when Pastor Weyel celebrated Holy Communion according to the Lutheran practices, the Reformed families severed their connection with the group.

On November 4, 1850, the German Ev. Lutheran Immanuel's Congregation was organized with fifteen men listed as charter members.

Johann Georg Geuther gave a gift of 20 acres of land at 88th Ave. & St. Francis Road. A small wooden church was built. Inside the church was the pastor's family's living quarters. The church served the congregation for 26 years.

During the first 23 years of ministry, Immanuel was served by seven pastors until in 1875 Pastor Elias Hieber was called to Immanuel and ministered here for 41 years until 1915. It was on Easter Sunday, in a congregational meeting that Pastor Hieber was granted a peaceful release from the congregation and also it was unanimously resolved to move to Mokena.

In 1916 Immanuel joined the LCMS - during the Northern Illinois District convention. It had no prior affiliation, although it was served by Missouri Synod pastors throughout its history.

In the year 1919 English services were introduced, the Ladies Aid Society was organized, Sunday School was reorganized and a day school also was opened and taught by the Pastor. Ten years later, however, the school was disbanded.

In 1939 the Ruth Society was organized. In 1948 a two-manual Wicks pipe organ was installed.

In the spring of 1955 land was purchased on LaPorte Road for "Building for the Future." The parsonage was built on this land in 1960. Finally in 1964 ground was broken for a new church building and the building was publicly dedicated on May 15, 1966. The outdoor worship center was dedicated on July 29, 1975. Membership was on the rise beginning in the 1970's.

Heritage Hall was dedicated on March 6, 1983 and this building allowed for fellowship and the space necessary for dinners and recreational activities.

Key anniversaries of the congregation were celebrated through the years. People have come and gone and the congregation has been served by 19 pastors through their 150 years, currently served by Rev. David P. Constien since 1995.
