5. (NOTE) (“Jesus” is a valid English transliteration, coming from Ancient Hebrew to Koine Greek (via the Septuagint) to Latin to Old English to Modern English. It is completely acceptable to God (Yahweh) for us call upon the Savior's name as “Jesus,” or “Iesous,” or “Yeshua,” or even “Yesu” as in Christian Arabic or in the Fijian Islands, et al. God prepared for all nations to be able to trust in the Savior and to call upon his name by preparing a language dialect for international use: the Hebraic-Koine Greek. Thus, technically and formally, the pronunciation “Iesous” was intentionally established by the Savior as the common basis for Jewish and Gentile acknowledgment of his Redemption and Salvation, going forth as needed into every tribe, native tongue, people, and nation. “Yeshua” is of course delightfully acceptable to him, when it is not used as an exclusionary name. Love edifies).
