The thesis of Carl Trueman's book is that creeds and confessions are a necessary part of Christian worship. He argues against the idea that the Bible is the only source of creeds and confessions believing that creeds and confessions are important adjuncts to scripture because they define the way the church interprets the scripture. Furthermore, creeds and confessions are public documents that allow for discussion and disputation about beliefs.
While I believe that Trueman has a good point about formal worship requiring a formal grounding, I found the book repetitious. He makes good arguments for the necessity for creeds as a succinct statement of faith. He also presents a short history of the Christian church's reliance on creeds as an adjunct to scripture which I found fascinating.
I can't recommend this book unless you are a pastor or lay person looking for illumination of the question of whether the Bible is sufficient or whether creeds are a necessary part of Christian worship.
I reviewed this book for the Amazon Vine Program.
