A Judaizer, a term NOT found anywhere in all of Holy Writ -- refers to someone who wants to bring believers into the bondage of Jewish man-made rules, the oral commandments and the Talmud.
A lover of Messiah is one who demands all humans to repent of all transgression against the written Torah (I John 3:4) and to place their full trust in YahShua who enables them to keep every jot and tittle of the written Torah (Matthew 5:17-21).
