My impression was that this was written mainly for clergy getting their activist feet wet. In that sense the book is an invaluable milestone. Because of this, it poses liberation (in the sense of liberation from oppressive social conditions like poverty and tyranny) as an intellectual issue, historically and theologically. Correction: it appeals to an intellectual understanding of what the author obviously has lived and felt very deeply.
Having just read LOVE IN A TIME OF HATE, I bought this book expecting to read flesh-and-blood examples of liberation theology as brought into the streets. You won't find much of that here. It's more of an account of how the movement has gone on in circles theological. As such, it poses vital questions to believers and clergy alike--questions of conscience, questions of the relevance of Scripture and the risks involved in living a Christian life of service and conscience in perilous situations.
