Uhmmm, excuse me but the word “worship” can be a noun, a verb or a title. You are clearly using the title meaning of the word.
Added note: no US American would ever use that word to address any one. I cannot speak for Canada but obviously in the UK the do use it.
From the Oxford dictionary:
noun . noun . /ˈwərʃəp/ [uncountable] 1the practice of showing respect for God or a god, by saying prayers, singing with others, etc.; a ceremony for this an act/a place of worship ancestor worship morning worship (= a church service in the morning)
Even point 2 of your own definition makes clear that worship is not exclusively religious in nature. Respect, honour and even devotion are.sentiments that one can give to ordinary people and not reserved for God alone.
