Empty Tomb Puzzle

[Neo-Scholastic]

You get past it by remembering (duh) that the whole thing is not a historical treatise but a synthesised, copied, edited story with absolutely no external validation from legitimate, contemporary sources?

1)Very very few writings from the ancient world would qualify as a historical treatise by today's standards.
2)To say they were sythesised and edited is pure speculation on your part.
3) John was made independent of the Synoptics. Each is a contemporary source for the other.

but how do you get past the simple solution that the priest had to put away Jesus once and for all by opening the tomb.

The argument from absence is very weak without additional support.
