The proof of the Bible is frequently posted on these pages as being evidenced by the fulfillment of prophecy. But the only prophecies which have been fulfilled are those in the OT which are fulfilled in the NT. (I asked a question earlier and this appeared to be the outcome - other than a vague prophecy about Jerusalem).
Are we not getting into dangerous circular argument territory here. OT verified by NT. QED.

There is already evidence that the Nativity story was "massaged" to make to make its prophecy appear fulfilled.
