if one reads anything they can justify their beliefs based on anything they wish.<quoted text>
If one reads the Bible to justify their beliefs they can make it say anything they want.
IMHO, only when you read it without prior assumptions can you derive a few possible interpretations no of which are any better than any other.
you can't read anything without prior bias; otherwise you would have no experiential knowledge of any sort; which would include the ability to read.
it's not asking you to suspend your beliefs, it's asking you to question your beliefs. the whole things is about mind & belief, and finally how it distorts the view point.
