θεός
theós · noun · “God”
Theos is the standard New Testament word for God — used both for the one true God and, strikingly, for Jesus, declared “the Word was God” at the start of John’s Gospel.
Theos covers any divine being in Greek usage, but the New Testament reserves it overwhelmingly for the one true God of Israel — the Father, but also the Son and the Spirit.
John 1:1 uses theos of Jesus directly: “the Word was with God, and the Word was theos.” The earliest Christians, all monotheists, made the breath-taking move of confessing Jesus as theos — God the Son.
Definition: figuratively, a magistrate; by Hebraism, very
KJV usage: X exceeding, God, god(-ly, -ward)
