I was disappointed in the content of the book. It has some very big holes in the chronology of church history. It was a waste of money, time and effort. I do not recommend it if you want well balanced charts of church history.
It is a very valuable tool, saves you time when you want to know about the beginning of Christian church history. If you teach or need to get a grasp on the church while reading the bible, I highly recommend this. B. Clark
