I also would like to point out the word "layman". It is being misused in our society.
It is a word that derives from old English from times when Priests only knew the language of the bible. Why Martin Luther printed his 95 Thesis.
Did you know about his other book?

The idiots that could not read or write in Latin were called LAYMEN. Today a Layperson is still a member of the church that is not part of the Clergy.

This is just my opinion. I know it matters not in this woke world.

Edit: I tried to watch the video but it is a 404 link?
