To say that those who use the English language and consequently refer to Easter as "Easter" worship Ishtar is like saying that those who go to church on Saturday do so to worship Saturn.
Yes, the planet-god names for the days are interesting.
Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn.
Most interestingly, they are uniformly linked to the same days across all cultures, which is one proof that we all came from a single Tower of Babel culture as the Bible says.
If I could change the names of the days away from those planet-gods, I would. The days won’t be called that in the Kingdom.
