Why John 1:1c Calls the Word "a god"

Given the grammar that we have at 1:1c, we may say that the only thing that can rule out “a god” would be a theology that has it that there are no real, begotten (created) gods. Contravention of such a theology is found at John 1:1b (the Word was with God, the Father), and John 1:18 θεὸν οὐδεὶς ἑώρακεν πώποτε· μονογενὴς θεὸς ὁ ὢν εἰς τὸν κόλπον τοῦ πατρὸς ἐκεῖνος ἐξηγήσατο. There at John 1:18 we learn that the Word is a god, the only god directly created/begotten by the Father; hence, he is called “an only-begotten god.” Only Jehovah God the Father is the unoriginate, unbegotten God. All other divine but created beings (superhuman creatures, angels) are gods, too (compare the Hebrew text at Psalm 8:5 with its Greek translation endorsed by the Scriptures at Hebrews 8:5); however, they are not gods directly created by the Father, but were gods/angels brought into existence by the Son, the Word, acting as the Father’s mediating agent for their creation. In fact, all anointed Christians who go to heaven will become sharers in divine nature (2 Peter 1:4 ἵνα διὰ τούτων γένησθε θείας κοινωνοὶ φύσεως); therefore, they will become gods, too. (Compare Romans 8:29; 1 Corinthians 15:49; Philippians 3:20, 21; Hebrews 1:3a.)

In the New Testament, the Greek word θεὸς, or the Greek phrase ὁ θεὸς, almost always refers to Jehovah, the only true God (of Universal Sovereignty; John 17:3), and this distinguishes Him from Jesus Christ because Jesus Christ is not the only true God of Universal Sovereignty, but was sent forth by the only true God, “the Father of all persons” (Ephesians 4:6). Jehovah God is the God and Father of Jesus Christ (2 Corinthians 1:3; John 8:54). In those cases, the Greek word θεὸς, or the Greek phrase ὁ θεὸς, does not refer to the Son, the Lord Jesus Christ (1 Corinthians 8:6).

Why, then, does John’s Gospel at 1:1 emphasize the Word’s godship, that the Word really was a god, a divine being? The apostle John’s Gospel account is unusual in that towards the end of the first century John was inspired to write things about Jesus Christ that would help Christians to combat a brand of apostasy (Docetism) that had it that Jesus was an agency in God that was manifested by God to human sight, as was true for the “dove” (holy spirit) that John the Baptist saw coming down to rest upon Jesus when he was baptized in the Jordan River (John 1:32). The Docetists said that Jesus was never a real being; however, John’s Gospel shows that the Word was not an agency in the Father’s being, but was already with God (the Father) as a god for the start of all those things that were to come into existence through the Word (in his role as the Father’s mediating agent) for their creation, and that this one (the Word) became flesh (John 1:14 Καὶ ὁ λόγος σὰρξ ἐγένετο), which was something that cannot be sensibly said about any agency in God’s beingness. The Word did not merely appear on earth as though he were like a creature of flesh, but the Word really was a god who became flesh; the Word became a real man, the man Jesus.
