PS - While that is an important point and a good example, it is also important to understand that the gospels and letters were NOT written or passed on in a " vacum ", one of the things that Paul does is stated that there were live witnesses to what he is preaching, witnesses that can be contacted to confirm what the gospel is and what Jesus said IN PERSON.
Granted, in regards to the copies we have NOW, we have no such gurantees , BUT the NT documents are viewed by the majority of historians as historically reliable in that, what happened was viewed by those that wrote it and passed them on as being historically accurate.
X - Not to be argumentative, but you make several assertions.
1. Witnesses that can be contacted? Are they not dead? If so, how can you contact them?
2. Gospels and letters were NOT passed down in a 'vacuum'? Are you sure about that?
3. Majority of historians view the bible as historically reliable? That is a pretty major assertion, don't you think?
