As a Baptist, I am from a non-creedal tradition. But we all summarize our beliefs. We can summarize it well as a community or poorly as individuals. The more ancient creeds I find more valuable since they point to our common heritage and faith. We need that reminder.
Of course, creeds don’t just express common beliefs but common issues. The Apostle’s Creed and Nicene Creed express a common faith, but also point out what we seen as deeply important at the time. For example, both of them speak about the nature of Christ, the birth of Christ and the Death, burial, and resurrection of Christ. Understandable that these are important. These are still the issues that schismatic groups challenge. There are, however, very important things about the life of Christ. Jesus is a teacher, prophet, healer, and model for the Christian. These really should not go unacknowledged in any creed.
Jurgen Moltmann’s addendum to these creeds are worth reflecting on. It may be wrong to change an ancient creed, but the Christian church has always been a creed-creating industry (even the Baptists do regardless if they are given less binding and timeless terms like “articles of faith” or “faith and message.”). Moltmann’s addendum seems a valuable addition to the ancient creeds, that they and we as Christians can wholeheartedly agree to. That being said, I doubt updated creeds will ever be done. The Filoque controversy points to how difficult it is to deal with even extremely trivial issues in creeds.
