Abstract
In this paper I focused on Johann Sebastian Bach’s Sunday services, Church Cantatas, and Catholicism in Leipzig in the 18th Century. First of all, I tried to examine the handwritten worship notes by Johann Christoph Rost, sexton at St. Thomas in Leipzig. Secondly, I treated of Bach’s Church Cantatas which were composed in the Leipzig era from 1723 to 1748 and I also investigated basic characteristics of Bach’s Church Cantatas in the 1720s BWV1, 1730s BWV51, and 1740s BWV69. Thirdly, I briefly touched on Catholicism as the subject of universal. And the reason I used Günther Stiller’s “Johann Sebastian Bach and Liturgical Life in Leipzig” (1982) is because this book includes concrete and credible expositions.
