Did worship in the Temple in Jerusalem take place only on the Sabbath?
That's not what I said.
What I said is:
Although I agree that we should worship the LORD every day of the week, it is very clear through Scripture that the Sabbath is something special.
Worship was a continual occurrence in the Temple of the Lord (and should be for us today since we are the Temple indwelt by the Holy Spirit).
The point I'm trying to make is that the Sabbath is special and should be treated as such. We are commanded to keep it holy and we honor the Lord by doing so.
