The title almost says it all:
What's the difference between the Gospel and The Bible? did one contain another of what?
What does each one include?
Where did every one come from (or who authored each, if possible)?
Please forgive my ignorance, if the question is encyclopedic then answering the first item is enough. If it's a duplicate then closing it is much appreciate. If there's anything wrong or disrespectful then I'm sorry and please point it so I omit it.
