It's on file in Bethlehem. Trust me on this. So, what's the name of the doc who signed it?
Alphabet has it right. Dr. Luke in his gospel, chapter 2 gives us the legal by Rome declaration of Christ's birth and also the Mosaic Law version (his circumcision and the required offering). Luke as an educated man nailed it in chapter 2 with the census (Rome) and then the visit to Jerusalem (Mosaic).
I don't know what version of software was used by Rome and the Temple in Jerusalem at the time, but Luke nails it firm with eyewitness interviews.
