You need to full understand what is really being said Wharton.
The angels of heaven are sons of God even as Adam was a “son of God.” (
Ge 6:2; Job 1:6; 38:7; Lu 3:38) But the
Lo′gos, later called Jesus, is “the
only-begotten Son of God.” (
Joh 3:18) He is the only one of his kind, the only one whom God himself created directly without the agency or cooperation of any creature. He is the only one whom God his Father used in bringing into existence all other creatures. He is the firstborn and chief one among all other angels (
Col 1:15, 16; Heb 1:5, 6), which angels the Scriptures call “godlike ones” or “gods.” (
Ps 8:4, 5) Therefore, according to some of the oldest and best manuscripts, the Lord Jesus Christ is properly described as “the only-begotten god [Gr.,
mo·no·ge·nes′ the·os′].”—
Joh 1:18,
NW, Ro, Sp.
A few translations, in support of the Trinitarian “God the Son” concept, would invert the phrase
mo·no·ge·nes′the·os′ and render it as “God only begotten.” But W. J. Hickie in his
Greek-EnglishLexicontotheNewTestament (1956, p. 123) says it is hard to see why these translators render
mo·no·ge·nes′hui·os′ as “the only begotten Son,” but at the same time translate
mo·no·ge·nes′the·os′ as “God only begotten,” instead of “the only begotten God.”
Paul referred to Isaac as Abraham’s “only-begotten son” (
Heb 11:17), even though Abraham also fathered Ishmael by Hagar as well as several sons by Keturah. (
Ge 16:15; 25:1, 2; 1Ch 1:28, 32) God’s covenant, however, was established only through Isaac, Abraham’s only son by God’s promise, as well as the only son of Sarah. (
Ge 17:16-19) Furthermore, at the time Abraham offered up Isaac, he was the only son in his father’s household. No sons had yet been born to Keturah, and Ishmael had been gone for some 20 years—no doubt was married and head of his own household.—
Ge 22:2.
