Stephan Kampowski, who co-authored the handbook, explains how the authors hope their work will provide a definitive interpretation in continuity with the Church’s magisterium.
I haven’t read the handbook yet but based on the interview and their declared dedication to follow the teachings of the Church and read AL from a proper hermeneutic of continuity and coherence it sounds like a solid interpretive tool. I really appreciate that they read chapter 8 in continuity with the rest of the document. Go-figure! The same thing we must do when we read Scripture. I guess some might consider that to rigid an interpretation of AL on AL.
The $18 price tag is a bit steep for me but if you find portions quoted on the internet send me a link.
