>>What fraction of the Bible makes up the Gospel?<<

It's all about Jesus.

>>Is the portion which is not “Gospel” to be discarded?<<

None of it gets discarded or added too or changed.

Now, about the subject of the thread. Have you found an infallible source showing that the apostles taught the assumption of Mary and the requirement to believe that?
