The congregation placed strong emphasis on the Christian instruction of its children and maintained a parish school for many years. On August 18, 1887, it authorized the trustees to purchase one acre of land for a school site. Herman Westenfeld taught from 1887, when the school was built, until 1890, and William Freytag taught from 1890 until 1915. When Freytag resigned because of diminishing strength, his son William Freytag, Jr., of Detroit was called to teach. In 1918 the system changed, and thereafter the pastor took charge by giving religious instruction during May, June, and July. The regular parochial school then ended, but concentrated religious instruction continued. Instruction was first given only in German, but English was later added, and in 1939 the first children were confirmed in English. German instruction remained available for some years to those who wanted it, but it was eventually discontinued and all instruction was given only in English. In 1940, when the Napoleon Public Schools extended their term from 8 to 9 months, religious instruction was reduced from 12 weeks to 8 weeks, and a Sunday School was organized to make up for the lost time. As the need for Sunday School space grew, plans for a Parish Hall were adopted on April 25, 1956, its cornerstone was laid on October 14, 1956, and the building was dedicated on July 28, 1957. The Parish Hall measured 48 by 115 feet, seated 480 for programs or 360 for receptions on the upper floor, and included a church office, pastor's study, kitchen, store room, Sunday School classrooms, and restrooms. Its approximate cost was $115,000.
