KAI BLEPEI TON LIQON HRMENON EK TOU MNHMEIOU
"and sees the stone removed from the tomb"
I assume that the perfect for HRMENON emphasizes the current state:
the tomb is open; the stone no longer seals it. If the writer had wanted to
vividly display the process of the stone moving, he would have used present or
imperfect; if the writer had wanted to emphasize the act of moving the stone as
a whole, he would have used aorist.
Is this accurate?
