Footnotes

1. 3:1–6 The letter to Sardis does not praise the community but admonishes its members to watchfulness, mutual support, and repentance (Rev 3:2–3). The few who have remained pure and faithful will share Christ’s victory and will be inscribed in the book of life (Rev 3:4–5).
2. 3:1 Sardis: this city, located ca. thirty miles southeast of Thyatira, was once the capital of Lydia, known for its wealth at the time of Croesus (6th century B.C.). Its citadel, reputed to be unassailable, was captured by surprise, first by Cyrus and later by Antiochus. The church is therefore warned to be on guard.
3. 3:5 In white: white is a sign of victory and joy as well as resurrection; see note on Rev 2:17. The book of life: the roll in which the names of the redeemed are kept; cf. Rev 13:8; 17:8; 20:12, 15; 21:27; Phil 4:3; Dn 12:1. They will be acknowledged by Christ in heaven; cf. Mt 10:32.
4. 3:7–13 The letter to Philadelphia praises the Christians there for remaining faithful even with their limited strength (Rev 3:8). Members of the assembly of Satan are again singled out (Rev 3:9; see Rev 2:9). There is no admonition; rather, the letter promises that they will be kept safe at the great trial (Rev 3:10–11) and that the victors will become pillars of the heavenly temple, upon which three names will be inscribed: God, Jerusalem, and Christ (Rev 3:12).
5. 3:7 Philadelphia: modern Alasehir, ca. thirty miles southeast of Sardis, founded by Attalus II Philadelphus of Pergamum to be an “open door” (Rev 3:8) for Greek culture; it was destroyed by an earthquake in A.D. 17. Rebuilt by money from the Emperor Tiberius, the city was renamed Neo-Caesarea; this may explain the allusions to “name” in Rev 3:12. Key of David: to the heavenly city of David (cf. Is 22:22), “the new Jerusalem” (Rev 3:12), over which Christ has supreme authority.
6. 3:8 An open door: opportunities for sharing and proclaiming the faith; cf. Acts 14:27; 1 Cor 16:9; 2 Cor 2:12.
7. 3:10 My message of endurance: this does not refer to a saying of Jesus about patience but to the example of Christ’s patient endurance. The inhabitants of the earth: literally, “those who live on the earth.” This expression, which also occurs in Rev 6:10; 8:13; 11:10; 13:8, 12, 14; 17:2, 8, always refers to the pagan world.
8. 3:12 Pillar: this may be an allusion to the rebuilding of the city; see note on v 7. New Jerusalem: it is described in Rev 21:10–22:5.
9. 3:14–22 The letter to Laodicea reprimands the community for being lukewarm (Rev 3:15–16), but no particular faults are singled out. Their material prosperity is contrasted with their spiritual poverty, the violet tunics that were the source of their wealth with the white robe of baptism, and their famous eye ointment with true spiritual perception (Rev 3:17–18). But Christ’s chastisement is inspired by love and a desire to be allowed to share the messianic banquet with his followers in the heavenly kingdom (Rev 3:19–21).
10. 3:14 Laodicea: ca. forty miles southeast of Philadelphia and ca. eighty miles east of Ephesus, a wealthy industrial and commercial center, with a renowned medical school. It exported fine woolen garments and was famous for its eye salves. It was so wealthy that it was proudly rebuilt without outside aid after the devastating earthquake of A.D. 60/61. The Amen: this is a divine title (cf. Hebrew text of Is 65:16) applied to Christ; cf. 2 Cor 1:20. Source of God’s creation: literally, “the beginning of God’s creation,” a concept found also in Jn 1:3; Col 1:16–17; Hb 1:2; cf. Prv 8:22–31; Wis 9:1–2.
11. 3:15–16 Halfhearted commitment to the faith is nauseating to Christ; cf. Rom 12:11.
12. 3:16 Spit: literally, “vomit.” The image is that of a beverage that should be either hot or cold. Perhaps there is an allusion to the hot springs of Hierapolis across the Lycus river from Laodicea, which would have been lukewarm by the time they reached Laodicea.
13. 3:17 Economic prosperity occasioned spiritual bankruptcy.
14. 3:18 Gold…fire: God’s grace. White garments: symbol of an upright life; the city was noted for its violet/purple cloth. Ointment…eyes: to remove spiritual blindness; one of the city’s exports was eye ointment (see note on Rev 3:14).
15. 3:20 Christ invites all to the messianic banquet in heaven; cf. Is 25:6; Lk 14:15; 22:30.
