Why Do We Have Creeds is one of a series of over twenty booklets on various aspects of the Christian faith. It is only a short book (42 pages) but it contains some profound statements about the nature of belief. Parsons states that our doctrine is the basis for the way we live (whether that doctrine or belief or faith is conscious or unconscious) and that we cannot be effective Christians if we try to isolate our doctrine from our intellect.While the basis of our faith is our relationship with God, Parsons calls the outworking of that faith 'religion' and points out that real faith, real religion affects the way we deal with others. This was an interesting idea to me, because many Christians I know take great care to point out that Christianity is a relationship, not a religion. Parsons effectively points out that one cannot exist without the other. We all believe something (even atheists and agnostics). Our creeds are simply statements of those beliefs. Quoting C.S. Lewis and St. Paul, Parsons makes the point that while an open mind is a useful thing, as Christians we believe in an ultimate foundation, and that to be open-minded about these basics can lead us astray.Although short, this is not simplistic. The ideas are complex, as is some of the vocabulary (thank goodness for the Kindle dictionary – except that this book is not available on Kindle and it should be). One point I would make - Parsons clearly beleives in the primacy of the Bible, which is classic Protestant theology. Those who do not agree with this may object to some of what this book says. Personally, I found it excellent.Thanks to P&R Publishing and NetGalley for providing a free ebook for review.This review also appears on my blog, www.christianreads.blogspot.com.
