Founded in 1940 by Bishop Joseph H. Albers, St. Thomas Aquinas was the largest parish in the Diocese of Lansing by 1988. The first Catholic parish established in East Lansing, it also served Okemos, Haslett, and Bath. The church took its name from the scholar St. Thomas Aquinas because it originally served as the Michigan State University
parish. During the pastorate (1943-1978) of Monsignor Jerome V. MacEachin, the present church she was purchased. The Parish school was opened in 1949 and the present church was dedicated in 1968. It features a mosaic of the Miracle at Cana of Galilee and a 45-five-foot-high faceted glass window depicting Salvation History as seen through the mind of St. Thomas Aquinas.
