I liked the first half, which explored the different ways to support the cause of Good, but I thought it lacked depth and I would have welcomed more discussion and examples of gameplay or stories in the campaign world for context. e.g. the illustration of Valeros in the Neutral Good section helped me understand what the writers were trying to convey. I found the second half less interesting, but those who enjoy technical details may find it useful.
My main gripe is that I expected a focus on Champions and the stuff that champions do, but I felt like I was reading the guide for Men-at-Arms or Sergeants for Purity.
There was some more interesting information, e.g. on heraldry, mounts and the names of equipment. There was also a roll call of the various groupings of knights in the campaign world. However, I never really got a sense of what made the Knights unique as a class, and they just seemed like fighters with a title. The art was gorgeous.
I found this player companion rather inspiring, in that it help me think about how faith in a campaign setting can guide player character behavior. I enjoyed the art, and the way the prose was written. I really did not need more charts and tables.
