John 21:25 And there are also many other things which Jesus did, which if they were written in detail, I suppose that even the world itself would not contain the books that would be written.
Well that was an easy one...
Does the Roman Church take credit for the OT as well? Jesus told his disciples the following:
Luke 24:44-49 KJV
And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me. Then opened he their understanding, that they might understand the scriptures,
And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
