What I want to say is that the church would be your hospital, the holy water would be your medicine, and the priest would be your doctor. But since "would be" seems too overused and redundant in the sentence, I want to say it like this:
"The church would be your hospital, the holy water, your medicine, and the priest, your doctor."
Which commas in the above sentence are redundant and should be removed? I have a similar confusion with the following sentence too:
"Ball comes from the Latin word, bull, which also means a male cow, or, in other words, an ox."
When there are too many commas in a sentence, what rule of thumb must one follow to determine which one to retain and which ones to discard?
