As I noted in post #69, the term Christ has a very specific meaning, The Anointed One. As far as Jews are considered, the current peiod of time is BC since they do not recognize Jesus as the Messiah. You can refer to Thursday (Thor's day), but that has no meaning theologically. Before Christ has a definite meaning.
This is your argument now, but at the beginning of the thread you said...
The use of BCE and CE provides a common measure.
So which is it? I believe you realized that you had lost the "common measure" argument and allowed your argument to change to the "it's offensive" argument. If that's your case, fine, but I want to note the shift in this position.
