Mr. Wallis, would Christ have entered a country illegally? Would he have committed fraud to obtain a driver's license or other government services he wasn't entitled to?
The Pentateuch says repeatedly that there was to be one law for the stranger and the Israelites alike: if the Gentiles joined the Mosaic covenant (i.e. assimilated) they were entitled to participate in the Passover, the sacrifices, and the rest of covenant life. Not before.
I would suggest there is a vast difference between a stranger and one who violates the law.
