In the ancient world, Greek was the international language of educated people. Every single time somebody wrote about Jesus before 100 AD they wrote His Name as Iesous every single time with no exceptions, other than abbreviations like IU. 100% of the time His Name is only written as exactly Iesous across all contemporary sources. Iesous was changed to Iesus in Latin and then Jesus in English. It is likely a Greek version of Yeshu or Yeshua or Yahoshua, which is a reference to YHWH. The name YHWH appears more than any name in the Bible but it is stripped of its vowels so nobody knows the full name of God. The two biggest guesses are Yahweh and Yehowah (Jehovah). The name isa was made up over 600 years later lol.
>>18555863Arab Christians call him Yasu. It's not clear why the Quran calls him Isa, the most compelling theory I've seen is that Muhammad altered the name to make it a rhyming pair with Musa(Moses), there are quite a few of these in the Quran.
>>18555863You're just scratching the surface. The name Jesus is made up in an effort to historicize him. The oldest manuscripts only used nomina sacra. The truth is that an abbreviation such as ΙΣ can stand for something else.The Quran's Isa is bizarre, but it must go back to the nomina sacra ΙΣ.
>>18555891If you wanna get deeper then yes ΙΣ is how they first wrote His Name before Iesous but ΙΣ can be an abbreviated version of Iesous. If you want to go deeper then, originally His Name was only spoken orally for the first 20 years before ever being written by the pen as far as evience concerns. But, if His Name were really something other than Iesous, why is there no written document calling Him something other than Iesous or ΙΣ from the time and place? Lol.
>>18555999There's this theory that ΙΣ is just a transliteration of the Hebrew word for man. אִישׁ • (ish). Then these stories about "Jesus" were originally about an anonymous supernatural man, probably meant to be identified with Yahweh. Early readers would see these stories as belonging to the same literary tradition of Genesis 18 or the time Jacob wrestled an "angel".>The "angel" in question is referred to as "man" (אִישׁ: Ish) and "God" (אֵל: El) in Genesis,At some point editors of the manuscripts wanted to merge this character with the name of Joshua, so later revisions started to reflect that.
>>18555863>Every single time somebody wrote about Jesus before 100 ADThey probably weren't very educated because Christianity was outlawed in the Roman Empire, and mainly practiced by easterners who spoke and wrote in their vernacular because they were not literate in Latin.
