I mean…to be fair a lot of people not raised in Christian households or communities wouldn’t be as familiar with Christian legends or the significance of certain objects, so their minds might not jump right to that.
But yeah…I was thinking piece of the True Cross as well.
Then again…it’s easy to assume it would be a Christian artifact because of all the talk of churches, but it might not be.
I’m trying to do some research, but does anyone more familiar with Islam know if there are significant wooden objects that might have healing powers connected to Islam?
