Isaiah 9:6 For a child is born unto us, a son is given unto us; and the government is upon his shoulder; and his name is called Pele-joez-el-gibbor-Abi-ad-sar-shalom;
This child which is born is called El-Gibbor, which as Im sure you know is ‘Mighty God’ and is never used of a man. Avi-Ad is literally Father of Eternity and could never describe a mere man. Some quotes for you
In the Targum of Isaiah we read: “His name has been called from old, Wonderful Counselor, Mighty God, He who lives forever, the Anointed One (Messiah), in whose days peace shall increase upon us.”
Midrash Mishle, S. Buber edition: The Messiah is called by eight names: Yinnon, Tzemah, Pele [”Miracle”], Yo’etz [”Counselor”], Mashiah [”Messiah”], El [”God”], Gibbor [”Hero”], and Avi ‘Ad Shalom [”Eternal Father of Peace”]
The great rabbi Ibn Ezra said: There are some interpreters who say that wonderful, counselor, mighty God, everlasting Father are the names of God, and that only prince of peace is the name of the child. But according to my view, the right interpretation is that they are all the names of the child. (Walter Riggans, Yeshua Ben David [Wowborough, East Sussex; MARC, 1995], p. 370)
Clearly, if this was the only verse, it shows that this child is called God. The Rabbis called the Messiah by the name God.
2. Jeremiah 23:5-6 ‘The days are coming, declares the LORD, when I will raise up to David a righteous Branch, a King who will reign wisely
and do what is just and right in the land. In his days Judah will be saved and Israel will live in safety. This is the name by which he will be called: The LORD Our Righteousness.
"For Child is born unto us, Son is given unto us; . . ."
Not coincidentally, in speaking to the Virgin Mary, Angel Gabriel called Him by the titles (also anarthrous) "Son of the Highest" and "Son of God." The definite article added by the translators is incorrect. Those are titles, more than merely proper nouns because the are names of Deity.
Of course, in each of these cases, the title "Son of God" means that He is not merely divine in quality, but Deity personified, and of the same substance as The Most High God and Father of Lord Jesus Christ/Messiach (cf Ephesians 1:3 as an example).
Thanks for this fine meditation, Bro. Bill. You've presented it very carefully to warn the unwary or spiritually immature Christian. To argue against your point is foolish, IMHO.
