“Somewhat of a strong question,” you may muse. Nevertheless, it is pertinent to our study of days as they relate to the Sabbath. God created all things, including humans in six days (Genesis 1:1-31). At this point we ill not enter into the debate concerning the length of creative days. God then rested on a seventh day, blessing and sanctifying it (Genesis 1:1-3).
Some teach that we must cease from any type of form of physical labor on the seventh day of our calendar, because God rested on the seventh day of the week. If this were the case, are we to rest on the same seventh day God rested on? If we are, then we must find out what day God began His creative work. Saturday is the seventh day of our Julian calendar. Can we prove that God began his creative work on Sunday, finished it on Friday, and then rested on Saturday? No. This information is not available to us.
We should also not that the names of days come from the sun, moon, planets, and pagan gods.
