Norland,
I am also reminded in your last sentence of the above response that sacred is the word scared all jumbled up, as if being scared can be the result of witnessing/experiencing something sacred–I love to call these “Word Scrambles.” When I have pondered this, I often feel that the word scared must have had many layers of meanings and not always just fear. Of course, it has the word scar in it, like anything that might leave a scar on our psyches, which may go along with what you write about the crucifixion never being able to undone. Certain things we see can never be unseen it seems.
