I’ve read several articles on the subject of the name of the Messiah. I remember coming across this piece (Link), and I quote [my emphasis added]:
“Yeshua is the Hebrew name, and its English spelling is “Joshua.” Iesous is the Greek transliteration of the Hebrew name, and its English spelling is “Jesus.” Thus, the names “Joshua” and “Jesus” are essentially the same; both are English pronunciations of the Hebrew and Greek names for our Lord. (For examples of how the two names are interchangeable, see Acts 7:45 and Hebrews 4:8 in the KJV. In both cases, the word Jesus refers to the Old Testament character Joshua.)
Changing the language of a word does not affect the meaning of the word. We call a bound and covered set of pages a “book.” In German, it becomes a buch. In Spanish, it is a libro; in French, a livre. The language changes, but the object itself does not. As Shakespeare said, “That which we call a rose / By any other name would smell as sweet” (Romeo and Juliet, II:i). In the same way, we can refer to Jesus as “Jesus,” “Yeshua,” or “YehSou” (Cantonese) without changing His nature. In any language, His name means “The Lord Is Salvation.””
Well, let me give you an example you might better relate to, seeing as a book is just a noun, not a proper noun, as a name would be (there is a huge difference as you’ll see).
So your name is John. You were born in England, and you visit South America. What do they call you? Well the Spanish version of John is Juan (pronounced ‘quan’). If they called you Juan, would you respond? I doubt it! If they call you by your name as it was given to you, you would know it was you they meant, even if their accent wasn’t very good.
If you were a Frenchman, and your name was Guillaume, and you come to Britain – what do we call you? We call you Guillaume – because that is your name. In England you would have been named William.
If you were called Jane, and you went to Bulgaria, and they called you by their version of Jane, which is Yana – would you answer?
You are not a book, you are not a table, you are a person with a proper noun as your name. According to the ancient texts, His name is Yeshua. I’ve had my own issues with the spelling of His name, because there have been many arguments over it, and I have finally gone with the name the Messianic Jews use, because they ought to know, being Hebrews.
Does it matter? Not as much as some would say – I know that those who pray in Jesus’ name are reaching Him, and that prayers are answered – I’ve seen it, and I’ve experienced it. It is not crucial, but it is a sign to God of our deep love for Him that we would care to call His Son’s name as it was in His day, and to attempt to find it out and call upon it, even if we say it wrongly, or even spell it wrongly – it is what is behind our doing this what God cares about.
I hope this is helpful, and doesn’t add to any confusion that has already been sown on this issue.
God Bless you
