An extract from the Catholic education research centre......... CERC. In answering this question the first thing to understand is what kind of documents the gospels are. To do this we have to first say what they are not. The gospels are not factual news reports. They are not a bald list of events and eyewitness testimony as might be compiled, say, in a police report: "Just the facts ma'am." They are not typical biography or the work of a professional historian. Neither are the gospels academic historical documents which are cross referenced with multiple documentary, archeological and anecdotal evidence. They don't pretend to be this kind of document, so it is ridiculous to blame them for not being so. I'm not blaming the gospels for their content, I'm simply sifting through one of them to discover an historical account. Now...... again...... 'Was the Gospel of Mark adjusted by Christians?'
