ἐν ἀρχῇ ἦν ὁ λόγος · καὶ ὁ λόγος ἦν πρὸς τὸν θεόν · καὶ θεὸς ἦν ὁ λόγος
“In the beginning was the Word, and the Word was with God, and the Word was God.”

For theosis

Passages read as affirming some form of human participation in the divine nature.

καὶ ὁ λόγος σὰρξ ἐγένετο
“And the Word became flesh and dwelt among us.”
Gospel of John 1:14 · Codex Sinaiticus · c. 90–110 AD

God entered humanity. If divinity can become flesh, the boundary between divine and human is permeable. The orthodox read this as unique to Christ; the Gnostics read it as paradigmatic.

Against theosis

Passages read as ruling out any real human participation in the divine nature.

μονογενὴς θεὸς ὁ ὢν εἰς τὸν κόλπον τοῦ πατρὸς
“The only-begotten God, the one who is in the bosom of the Father, he has made him known.”
Gospel of John 1:18 (Sinaiticus reading) · Codex Sinaiticus · c. 90–110 AD

Sinaiticus reads 'only-begotten God' (monogenes theos), not 'only-begotten Son.' If Christ is the unique God, divinity may be his exclusive property. Key textual variant.

“Cattle die, kinsmen die, you yourself shall die. But the fame of one who has done well never dies.”

Norse pagan immortality is not theosis but reputation. Glory outlives the body where the soul does not.

ἐγὼ καὶ ὁ πατὴρ ἕν ἐσμεν
“I and the Father are one.”
Gospel of John 10:30 · Codex Sinaiticus · c. 90–110 AD

The neuter 'one' (hen, not heis) means 'one thing,' not 'one person.' Unity of substance or merely of will? The Arians, Nicenes, and Gnostics all claimed this verse.
