Let me start by saying that The Starfish Manifesto (press the link to download it) is not really a book. It's more like a draft of a book, with many parts that would (and probably should) be changed and cut before becoming a book. Which means it is not easy to read, and it is really long. Only the really interested soul will be able to finish it (like I did, and no one else I know was able to).
The Starfish Manifesto starts where Houses that Change the World stopped. It is focused mainly on the prophetic and apostolic gifts, and how the strategy of God to the discipling of the planet can operate through those gifts.
The book starts describing the roles of the prophet and of the apostle, and then how those roles work together for the envisioning of the strategy of the church, locally as well as globally. It finishes with some practical wisdom in how to make the jump. I identified a lot with what is written in the book, except with the financial principles.
This book, together with The Forgotten Ways, are at the moment, in my opinion, the ones that best describe the vision of God for the church of today. A organic, Christ-centered, Kingdom of God oriented, apostolic, missiological church.
I am a big supporter of the house church movement. I support it, I advocate it, and I live it. So, for me, this book didn't bring much new, it was more a question of hearing someone describing part of what I'm living. But for someone that is not in it, this is an excellent book to read. It gives you the reasons for why we believe we have to return to the house church model of church.
On the other hand, in my opinion, Simson's opinion is too strict for my taste. Specially concerning his view of the "fivefold" ministry and the way he believes house church is the only way to go. God can move in many different ways. I also dislike the way he uses numbers to show that the house church is the right thing to do. The reasons have to be more profound than that. But well, that's the problem with books. If I was talking with him face to face, maybe we would end up realizing we think the same way. Books don't give much room for dialogue.
I recommend this book for anyone frustrated with the institutional church, and that wants to learn more about other ways of being church. This is a great book to give you a general idea of what the house church movement is.
