The roots of The Lutheran Church began in 1517. The roots of The Lutheran Church Missouri Synod, LCMS, trace back to 1847, when Saxon and other German immigrants established a new church body in America, seeking the freedom to practice and follow confessional Lutheranism. Lutheranism is a major branch of Protestant Christianity which identifies with the theology of Martin Luther (1483–1546), a German friar, ecclesiastical reformer and theologian. Lutheranism advocates a doctrine of justification "by grace alone through faith alone on the basis of Scripture alone". LCMS confesses that scripture is the final authority on all matters of faith. These lectures listed here teach, provide and discuss, in part, the history of this denomination of Christianity.
