Concerning the possibility of a pregnant Mary traveling long distances when just before term, while perhaps arguable it doesn't seem a particularly strong argument to me. What percentage of woman could make such a journey? I have a feeling the answer is not 0%. The historical arguments seem much stronger.
The historical arguments expressing doubt that the Romans (or anyone, for that matter) would ever conduct such a census, and concerning whether a Roman census of any kind would ever be conducted in a nominally independent vassal state, and concerning the timing of Quirinius's governorship and Herod's period of rule and so forth, these seem like much stronger arguments than doubt about Mary's ability to travel.
In any case, Egyptian records show that registration took place where property was owned, and Joseph presumably owned property in the Bethlehem area.
For a Roman census you seek Egyptian records about property registration?
This thread seems to be mostly guesswork...
Well, I guess now it has guesswork.
If Jews and Romans could not diss this account...
Skepticism and doubt about the Jesus mythology were widely expressed at the time. Someone here recently went to the trouble to provide references, though not in this thread. Anyone remember where that was?
