Here’s how I see it. All babies look like Winston Churchill.
Churchill had an English father and American mother. Jesus was half human, though without sin. The Son of Man, and God.
And he had a number of siblings: “Is not this the carpenter’s son? is not his mother called Mary? and his BRETHREN, James, and Joses, and Simon, and Judas? And his SISTERS, are they not all with us? Whence then hath this man all these things?” Matthew 13:55-56
Common experience tells us that the birth canal is not a one way street—there’s no such thing, at least in our species, as parthenogenesis. Mary was “intact” when she became pregnant with Him—if you ignore the passage about what a swell guy Joseph was for marrying her even though she was, um, in a `delicate condition’—because she was artificially inseminated by an Angel, right? So Jesus had to be the oldest and, well, there it is.
I hope that clears things up for you all.
