“Does the article say this? I don’t see it.”
No, you don’t.
“Also, wasn’t this monstrance just recently been made known to the public?”
No, not really, but that wouldn’t be the point anyway. Clergy would recognize it more readily than lay people anyway.
“If so, isn’t it possible that someone who could recognize it just hasn’t seen it yet?”
Yes, but most likely it hasn’t been recognized because it is old.
Vladimir: No, you don’t.
I'm not sure you answered the question or if you're just saying I didn't see it. Was it in the article? If so, could you post it?
