Etymology of the days of the week

A linguist's brain is always dissecting language. I find that I learn language better when I know the root meaning of a word. It is often a fun game to then learn all of the other words connected to a root meaning, or a word tree, so to speak. I have a bit of a personal theory that words carry on the psyche of a culture and previous generations as we pass them on to the next. It's a hard theory to prove and I have other things to work towards that are more important such as saving endangered languages.
I did get to thinking about the days of the week. It is pretty easy for an English speaker to see that Sunday is named after the sun and Monday is named after the moon. Thursday is named after Thor (Norse god) and Saturday after Saturn. But what are the other days named after?
I did a bit of a search and discovered that all of the days of the week are named after Germanic, Norse or Roman gods.

Sunday: named after the Germanic sun goddess "Sunne."
Monday: named after the Germanic moon god "Mani" (old English "Mona").
Tuesday: named after the Norse god Tyr (or Mars) became Twis in old English.
Wednesday: named after the Germanic god Woden or Norse god Odin, who is Mercury.
Thursday: named after the Germanic god, or Norse god Thor, who is Jupiter.
Friday: from the old English Frige meaning Venus.
Saturday: from the old English Saetern or Saturn.

While it is true that all of the days of the week are named for bodies in the heavens, they were also named for pagan gods. The concept of a heavenly body and a god were one and the same to the ancient peoples who gave the names. This pattern of naming the days is the most common through out all languages of the world. The pattern is broken in cultures that experienced a spiritual awakening in ancient times.

Russian is a language that does not name the days of the week for pagan gods. Russian names the days of the week largely based upon the numbering system.

(Sunday) Воскресенье, (Voskreseniye) -Meaning resurrection, referring to the resurrection of Jesus Christ from the dead.
(Monday) Понедельник, (Ponedelnik)- All other Slavic languages call Sunday "Nedelya", literally no business or no work. Sunday is the day of no work. Ponedelnik is the day after no work. Interestingly, Russian is the only Slavic language to use the word resurrection to refer to Sunday. Russian uses the Slavic word for Sunday, "nedelya" to refer to "week."
(Tuesday) Вторник, (Vtornik)- literally, the second (day).
(Wednesday) Среда, (Sreda)- literally, the middle. This however is inconsistent with Tuesday being numbered second.
(Thursday) Четверг, (Chetverg)- literally, the fourth (day).
(Friday) Пятница, (Pyatnitsa)- literally, the fifth (day).
(Saturday) Суббота (Subbota)- literally, the Sabbath,

The Russian language really came into birth after 800 AD and was still a very young language by the time of official Christianisation in 988 AD. So any usage of Old Slavic pagan names for days of the week would have been quite obvious to early Russian Christians. I have tried to research on the internet Old Slavic names for days of the week and have been unsuccessful at turning anything up. Early Russian Christians would have had a strong desire to change the naming system fo days of the week.

There are two basic systems for naming days of the week- numbering or pagan gods. There are some religious variations, work based variations and legal based variations in various languages. There is no system that uses a "world" religious name for every day of the week. The Irish language uses Lord's Day for Sunday, First fast for Wednesday, Day between fasts for Thursday and Fast for Friday. It maintains the planets/ pagan gods for the remaining days.

Many Muslim countries have changed their languages throughout history to a numbering system (this is a supposition of mine, I would have to check up each respective proto language to confirm this), while often referring to Friday as a meeting or gathering day.

My question is, how important is is that English days (and many other languages) are named after pagan gods? It could be argued that it is not important, because language changes and people do not think of pagan gods when naming days of the week. But is this really true? On a latent level many of us know that the days are named for pagan gods. Of course, western societies by and large are not majority Christian any more, so there would be no desire to change the system for a majority of people.

The Quakers were a deep thinking people and decided to drop the pagan system and change to a numbered system- Lord's Day, second day, third day etc. The Hebrew days of the week were first day, second day, so on and Sabbath for the seventh day. One day, when there is a great spiritual awakening in the nations of the west again (which I theologically believe there will be), I wonder if the names of the days of the week will be changed accordingly.
