Netzarim are followers of Yeshua (Jesus) who kept Torah.  In my most humble opinion, I do not believe early believers in Yeshua called themselves “Christians.”  I believe this is an arrogant attempt by the church to replace the “Jewishness” of our New Testament.  Also, notice in this video the written stone is in Aramaic, not Greek.

Other resource… Was the New Testament Really Written in Greek?
