August 4, 1821
Reverend William C. Blair was the first Sunday school missionary of the United States. A Sunday school missionary was one responsible for leading and organizing Sunday school programs. He began this work in August of 1821. In his first year, he traveled 2,500 miles, mostly on horseback, visited six states, and founded 61 Sunday schools, four adult schools, and six tract societies. He later apologized as illness kept him from doing more.
The Sunday school movement in the United States was inspired much by Robert Raikes’ work in England during the 1780s to provide poor children with basic education and religious instruction on Sundays (their only day off work). William Blair was a Presbyterian layman who believed “there ought to be eight or ten Sunday-school missionaries in every state.” Through his work, reading and writing (through the Bible) was taught, especially in very rural areas. Children were taught moral instruction (discipline, prayer, and Christian ethics). Sunday schools began to become the first point of contact for families that would later join churches. The American Sunday School Union would be founded in 1824 with the mission of “A Bible for every home, a school for every child, and the gospel for every soul.”
