Formal and Material Principles

Encore Post: It sometimes happens at a wedding reception, a dinner party or other social event. You are sitting near someone you’ve never met before. During the polite small talk, you learn your new friend belongs to a church you’ve never heard of before. If you are a curious person, you might ask about it. After learning a few surface details, you move on to another topic. When you get home, you are quite confused and cannot figure out how it all fits together. You’re not alone. Unless you have some place to begin to make sense of it all, it is easy to get lost when talking about what a church believes — including your own!

The teachings of a religion are almost always connected one to another. A pastor, priest or other religious leader can begin at virtually any teaching and explain all of the rest of what they believe in terms of it. If you look at number of formal books of theology — especially systematic theologies — you will notice they begin at different places. Some begin with talking about God and His traits (in theological language attributes), others begin with definitions and other concepts needed to understand what Christians believe (prolegomena). Some begin with Christ, still others take up salvation first. Where they start can tell you a lot about who they are in and of itself.

When I’ve spoken to others about what Lutheran Christians believe, I’ve found it useful to begin with the Formal and Material Principles of Lutheranism. A formal principle is the source that a faith turns to as its final authority on what to teach and how to live. A material principle is what a faith is made of — the central principle which explains everything else that it teaches.

For Lutherans, the only source and authority for what a Christian should believe is the Holy Scriptures, the Bible, alone. Our Material principle is all about God’s grace and how Christ earned for us salvation. The disadvantage of beginning here is it starts without explaining sin, how people got lost in the first place, who God is and what he’s like and many other truths. The advantage is it majors in the majors.

What is it?

When Martin Luther visited the churches of Saxony, he discovered that everyday people knew very little about the Christian faith. To help pastors and parents learn the basic truths of the Christian faith, he wrote a little book called The Small Catechism.

A catechism is a book which uses questions and answers to teach people about the faith. One of the most common questions Luther asked in his catechism is: “was ist das?” which means “what is it?” or “what does this mean?”

This blog is named for this question. My goal is to share the Christian faith in an organized way. I hope to provide for you a way to remember the details of what Christians believe, to make sense of more formal writings in Christian theology and understand how such teachings relate to each other. In scholarly language, this is called systematic theology.

In order to be straight with you, let me tell you a little bit of my background. I am a Confessional Lutheran clergyman, a member of the Lutheran Church–Missouri Synod. I serve as the Electronic Resources Librarian at Concordia Theological Seminary, a graduate school of theology. We prepare pastors and deaconesses for service in the church and provide advanced education for missionaries and leaders of the church. Before coming to serve here, I served as a pastor for two small town Indiana Lutheran churches. I also served as the Archivist and Historian of the Missouri Synod’s Indiana District. I occasionally write for The Lutheran Witness magazine and other periodicals. I use my Facebook profile (https://www.facebook.com/cosmithb) as a way to be a reference librarian in the 21st Century, sharing resources my Facebook friends find useful.  

Expect that my assumptions, viewpoint and leanings will come from that background. While my comments here will be faithful to the Bible, Lutheranism’s confessions as contained in the Book of Concord, and the doctrinal statements of my church body, this blog is not an official statement of the Lutheran Church–Missouri Synod or my seminary. These words are solely mine.
