where does the words minister, pastor, monastary, soloman, come from etymologically?

does this mean that christians are really studying astrotheology?

The word minister is etymologically rooted in a Latin word meaning "to serve," "to be a servant," or "to be near at hand to offer assistance."

The usage of pastor comes from its use in the Bible. In the Hebrew Bible (or Old Testament), the Hebrew word רעה (raʿah) is used. The word is used 173 times and can describe the feeding of sheep as in Genesis 29:7 or the spiritual feeding of human beings as in Jeremiah 3:15.

The word monastery comes from the Greek μοναστήριον "monasterion", from the root "monos" = alone (originally all Christian monks were hermits), and the suffix "-terion" = place for doing something.

These words have Latin, Hebrew, and Greek derivatives. I don’t see how these point to Christians studying Astrothrology.
