“18 And unto the angel of the church in Thyatira write; These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet are like fine brass;” (Rev 2:18)

The title used here is “Son of God”. This is the only mention in Revelation! cross-reference Peter’s own confession (Mt 16:16-18) vs. “Queen of Heaven” (is this Jezebel?) Jesus asserts His power and authority for judgment: The idioms “eyes like fire, feet like brass,” are similes or symbols of judgment! This is the central letter (fourth of the seven).
