The great biblical theologian Karl Barth entitled his magnum opus, Church Dogmatics. The multiple thick volumes of Barth’s Dogmatics were in 2oth century theology a watershed that held back the tide of liberal watering down of the biblical message. His work helped restore Christian confidence in the basic story of the life, death and resurrection of Jesus Christ.
For this coming Sunday, the “Baptism of the Lord,” the text from Acts chapter 10, verses 34-43, stands in place of an epistle reading and rehearses that basic story of the life and work of Jesus. It is a kind of mini-dogmatics. Peter’s sermon capsulizes Luke’s Gospel and looks very much like what was preached earlier in Acts by Peter as well as by Stephen and Philip in various contexts. There in chapter 10 the context is Peter speaking to the household of a Gentile, the Roman centurion Cornelius.
It’s fairly clear that Peter and the other early Christian witnesses accepted this basic story of Jesus: His anointing by the Holy Spirit; His miracles; His death by crucifixion (“hanging him on a tree,” verse 39); His resurrection from the dead; His authority to judge; forgiveness of sins in His name. It’s a brief statement of what Christians came to call “dogma,” settled opinion essential to genuine Christian faith.
However, in modern times the word “dogma” and being “dogmatic” fell into very poor repute. It began to imply “acceptance of authority without adequate grounds” (from an old Webster’s dictionary). Even in Barth’s time it was an unusual and bold move to deliberately label one’s work as “dogmatics.”
Yet there is a place for dogma in Christian life. If we are going to center ourselves around the person whom God calls His “beloved Son” in the Gospel for Sunday, Matthew 3:17, then the basic facts about who He is and what He did will be essential for us. It makes sense to be “dogmatic” about those things.
What we need to be less dogmatic about are issues just like the one surrounding Peter’s preaching in our text. Shall only those from a certain background and who embrace a certain very specific form of life be welcomed into the company of those receiving that dogmatic good news? For Peter it was the question of bringing the message to Gentiles and sitting at table with them in violation of Jewish dietary restrictions. For us, it may be a question of whether we genuinely wish to share the good news of Jesus beyond our own racial and cultural circles and practices and be in actual fellowship with others outside those circles.
As thoughtful Christians have always understood, we need to be dogmatic, but only about the things which really matter. Of course, sometimes discerning what really matters will be difficult and full o disagreement. But at least we know what remains at the core of it all. Thank you, Peter.
