(To original poster; ----please do not close the thread ---- yet): If you back up a couple of pages from p88, where you see the reference to “Spiritual North Star”, to the section heading “Keeping the Goal in Sight”, from thenceforth you can see that what he means by “Spiritual North Star” is simply “Holiness”, or perhaps “the Call to Holiness”, depending on the specific context over those two pages or so. This is a legitimate Catholic concept.
I do not think this Matthew Kelly has any claims to be a visionary as you might fear. This man is actually a renowned business consultant / motivational speaker, but I have never heard him referred to as a visionary. That is not to say he isn’t, but I tell you truth when I say I have never heard that description.
To the idea that, one should read all the Bible before any other spiritual books (which is what your concern is logically equivalent to), well certainly that would be a recommendable plan, but to say that to not read the full Bible yet take on (say) The Screwtape Letters (which I am in the midst of) in the meantime is to be condemned, is weak at best. I for one never felt, upon rereading three (!) times, that he reduced the Bible’s credibility.
This book does not have the imprimatur or anything like that. Perhaps appropriately: I think it has some weaknesses – in particular, he tends to oversimplify some background information while making a point. In several occasions he refers to “the media” as if that was some monolithic concept, which of course it is not. Probably more problematic is that on a couple of occasions he uses language suggesting he supports the heresy of Manichaeism (that is, “body bad, spirit good”). I for one like to assume he was making a rhetorical point, but would undertand if someone took issue with his presentation there.
I do believe his idea of “become the best version of yourself” is an immensely powerful pastoral meme useful today, and his recognition of the heresies of individualism, hedonism, and minimalism are very useful and accurate. I would fully recommend this book, especially to those catholics who want to be faithful but are having a weak period in their life. The introduction alone should be required reading to all Catholics, IMHO.
