Mark uses the term worship to refer to any religious gathering. I say it is limited to religious veneration, submission, adoration, or reverence of a diety (2,7,10) or as a metaphor (1,3,5,6,8). I need to discuss this further with him. I don't remember exactly what he said.
The point is: if I was a diety, I would not want to be worshipped. This is why I don't like the term.
