This book is aimed towards new Christians and wants to give them guidelines on how to find a good church to attend. The book has an English and a Spanish part, so that the book can be used with both speakers of English and Spanish. The content of both parts is identical.
The author seems to come from the Charismatic/Pentecostal direction. This heavily influences his position, especially on the gifts of the Spirits and he also includes a lot of implicit criticism against the Catholic church. And unfortunately, this limits the applicability. I don't want to say that he is wrong, not at all - but if you're a new Christian and you want to get an overview over all the different denominations, this book is not for you. I think that the book might be really great and useful for a church that has a similar theology. They could use it for new members to explain their positions and as an introduction into Charismatic theology. But this book wasn't for me.

Felt a bit judgey and like they were telling you things had to be done a certain way! You DONT have to go to church to be christian but you need to have some form of gathering.
