The term was originally "Vulgar Era" (meaning "the one that the people use", as opposed to the aristocracy which dated from the reign of various kings). Jewish academics started using "Common Era" to mean the same thing as "Vulgar Era" in the mid 19th century. "Christian Era" has never been used academically. It presumably came about due to people guessing at the "CE" in academic texts". It's not wrong though, so there's no problem. Also, unlike "Year of our Lord", it doesn't align the author with Christianity; it is merely factual.
