If I understand you correctly the answer to your question is yes, for primarily the real names of the Almighty and his Son.So you go with an Hebrew or Aramaic book of Matthew that was then translated into Greek? Jsut wondering.
I don't have an issue with assuming His Name in Hebrew was Yah-shua or something like it, just that there is no Scriptural authority per se, but you can make a case, but the real authority is in calling Him Jesus.
Much love!
I do use of course the Greek or even Latin Vulgate forms of scripture as that is what I have to work with, and they are transformed into the modern forms since the last several hundred years. And then I write my own side notes when I encounter deliberate alterations and bias supporting a religious stance or hypothesis that I consider intellectual dishonesty and down-right forgery. I do not have the originals of scripture in front of me, and then I would not understand them...have to rely on translators and scribes...
