The real problem with The Bible (and similar religious books) is not what is in the book, it is that each of our minds works differently. Each has different 'knowledge' and each 'thinks' something different than others.
The Bible may be close to perfect, the people who read and interpret it are not. Therein lies the confusion.
Well, after the first paragraph I had what I call a spiderweb moment. When I have those I generally gather scattered info and converge it. With the Bible, if those thoughts are not checked against the WHOLE Bible then we are in danger of adding to scripture. Every believer should be checking what is taught against what has been said by God. No listening to clips and thinking the whole scene is being witnessed. I love my concordance.
