I never thought I'd say it but I'm reading a book by Mark Shea

It's actually quite good so far and a lot of research went into it.  A LOT of research.  And it's written in a very conversational tone.  I've lost my love for Mark Shea over the years, but this may bring me back.

I'll report back later but as it stands this could very well be a "foundation book" along with Pope B16's Jesus of Nazareth for prospective Catholics.
