The term "Common Era" (CE) is an attempt to erase the historical basis for the primary calendar dating system in the Western world. "Common Era" has no real meaning, and even the origin of this term is unclear.
The established calendar dating system is based on the approximate birthday of Jesus, and no one disputes that. But this birth did not begin a "common" era, or any immediate change in history. The Merriam-Webster dictionary gives a date of 1889 for the origin of the term "Common Era," without indicating who began using it then, and why.
The only plausible explanation is that "Common Era" is an attempt to erase recognition for the Christian basis of the calendar. But there are not similar attempts to erase non-Christian religious names in the calendar, such as the days of the week named after Norse gods.
The conclusion is obvious: usage of the term "Common Era" seeks to deny recognition to Christianity. Beware of other examples of this, and beware how schools and tests are converting to "Common Era" dating systems to appease hostility to Christianity.
Consider this frank question and answer with a rabbi about the use of "Common Era," which illustrates that the term "Common Era" did not come from Judaism:
I would like to know why we say "before the Common Era" and "Common Era" (BCE and CE).
I mean, why do we call it "common?" ...
Dear Viviane ,
When I was a school boy I thought that CE stood for "The Common Error."
Now, 25 years and a number of common errors later, I assume that Common Era simply means "the date commonly accepted and used." But the truth is that I don't know, so I asked your question to a professor of European history. He didn't know either.
