A few pointers:
Some of the examples are typical: first it's Mary as having the child by a village lad (*fnarr fnarr*), so none of that god stuff, so Jesus is not the son of god so Redemption and Salvation have no meaning, he's just a bloke. ...hmmm do I see the very basis of Christianity being attacked here? Second, he presents a false dichotomy, between the simple moralist of Galilee - nothing divine, nothing special, there are plenty of moralists and always will be; and the Man Who Wants a Mighty Church to rule everything. This of course is a wild perversion of christian doctrine, the church is a means, not an end, only in Pullman's caricatures is the Magisterium a ruthless theocracy with power as its sole objective.
