And I wanted to ask how to answer correctly the claim about the changig style. (It is from about 31:30 and lasts a few minutes)
Something I’ve noticed from folks who reject Christianity and turn to another religious tradition: it’s less a rejection of Christianity itself, but rather, a rejection of a fundamentalist-literalist approach to Christianity. Having rejected that literalist view, they think that Christianity itself is false.
(He makes the claim that “in Christianity, you cannot ask questions” and the response is always “don’t let a little knowledge wreck your faith”. It’s clear that this is
not what Christianity teaches or recommends (although there are certainly individuals or groups within Christianity who say this).)
He also makes the error of attempting to read the Bible without context.
To your question: why would differences in style be a problem? He makes the claim that there are errors – and worse, deliberate and calculated modifications! – that people introduced over time. His claim has a germ of truth, but he’s spinning it really,
really hard…
The response, I think, is that although there were authors and redactors, we wouldn’t say what his friend is claiming: namely, that people deliberately attempted to change the Word of God in order to further their personal goals.
