Mike Pfefferle starts a new adult Sunday School class, “Studies in the Trinity.” You might think that you only need to know about the Trinity when “those people” ring your doorbell. J.I. Packer would disagree; he writes in Knowing God that “the heart of the Christian faith in God is the revealed mystery of the Trinity.” In this class, you’ll learn the Biblical foundation for the doctrine of the Trinity, how the first Christians worked to express the Biblical teaching in their own words, and how our God’s triune nature shapes every aspect of our Christian lives.
