TRADITION VS SCHOLARSHIP
The answer
Matthew seems to assume the family already lives in Bethlehem — there's a house, and only after Egypt do they resettle in Nazareth 'being warned in a dream.' Luke starts them in Nazareth and brings them to Bethlehem for a census, then home again.
Why it’s interesting
Both roads arrive at Bethlehem, as the tradition expected of the Messiah, but the journeys are quite different. Reading the two nativities in parallel — rather than blending them into one pageant — is where the scholarship begins.
Genuinely debated
You can know the Bible.
Not just the stories, but the history, authorship, and scholarship behind it.
