Charles Ellicott Commentary Revelation 2:18

"And to the angel of the church in Thyatira write: These things saith the Son of God, who hath his eyes like a flame of fire, and his feet are like unto burnished brass:" — Revelation 2:18 (ASV)

Thyatira was situated between Pergamos and Sardis, a little off the main road that connected these two cities. It was a Macedonian colony, founded by Alexander the Great after the overthrow of the Persian empire.

The Macedonian colonists appear to have introduced the worship of Apollo, honored as the Sun-god, under the name of Tyrimnas. It has been thought by some that the description here given of Christ—"the eyes of flame"—was selected in allusion to this worship of the Sun-god, under the form of some dazzlingly ornamented image. Certainly, close commercial intercourse connected the daughter colony with its mother city.

There seem to have been various mercantile guilds in the colony—bakers, potters, tanners, weavers, and dyers. The dye trade was, perhaps, the most important. Lydia, the seller of purple, was in all likelihood connected with the guild of dyers; and her appearance in Philippi is an illustration of the trade relations of Macedonia and Thyatira. The Christian community at Thyatira may have owed its beginning to her. "She who had gone forth for a while, to buy and sell, and get gain, when she returned home may have brought home with her richer merchandise than any she had looked to obtain" (Trench).

The population was of a mixed character, including, besides Asiatics, Macedonians, Italians, and Chaldeans. The message that is sent to the Christians dwelling among them is from “the Son of God.” This is noteworthy when we remember how persistently the other term, “Son of Man,” is used throughout the Book of Revelation, and that here only is the phrase “Son of God” used; but it suits, as does the whole description, the message that breathes the language of sovereignty and righteous sternness. The eyes of flame will search the reins and the hearts (Revelation 2:23); the feet of fine brass will tread down the enemies and smooth the path before them, who will have power over the nations.
