"People celebrate lots of things."
Not in the Church.
"That is different from worship. That's why there are two different words"
The words are very similar. Worship IS a form of celebration.

True enough. Worship is a form of celebration. Worship is also reverent love, it is honor, and more. Not all celebration is worship. For example, birthday celebrations are not worship, yet they are celebrations.
