@jimfurr , I appreciate your zeal.
Yes, Hebrew/Aramaic is the original language. Just remember, Holiness is not about language, but about meaning and action. The Holy Spirit descended upon the apostles and they spoke different languages (even pagan languages). Those who heard it in their language understood the meaning and took action by repenting and becoming immersed in water.
I find the meaning of Yeshua to be fascinating and I think something is lost when the name is changed to Yahshua, since He was given His name by the Father with a specific purpose and meaning.
And you shall call His Name Yeshua (Yod-Shin-Vav-Ayin) for he shall save (Yod-Vav-Shin-Yod-Ayin) His people from their sins. Matt 1:21
