7. Philadelphia--in Lydia, twenty-eight miles southeast of Sardis, built by Attalus Philadelphus, king of Pergamos, who died A.D. 138. It was nearly destroyed by an earthquake in the reign of Tiberius [TACITUS, Annals, 2.47]. The connection of this Church with Jews there causes the address to it to have an Old Testament coloring in the images employed. It and Smyrna alone of the seven receive unmixed praise.
      he that is holy--as in the Old Testament, "the Holy One of Israel." Thus Jesus and the God of the Old Testament are one. None but God is absolutely holy (Greek, "hagios," separate from evil and perfectly hating it). In contrast to "the synagogue of Satan" (Re 3:9).
      true--Greek, "alethinos": "VERY God," as distinguished from the false gods and from all those who say that they are what they are not (Re 3:9): real, genuine. Furthermore, He perfectly realizes all that is involved in the names, GOD, Light (Joh 1:9; 1Jo 2:8), Bread (Joh 6:32), the Vine (Joh 15:1); as distinguished from all typical, partial, and imperfect realizations of the idea. His nature answers to His name (Joh 17:3; 1Th 1:9). The Greek, "alethes," on the other hand, is "truth-speaking," "truth-loving" (Joh 3:33; Tit 1:2).
      he that hath the key of David--the antitype of Eliakim, to whom the "key," the emblem of authority "over the house of David," was transferred from Shebna, who was removed from the office of chamberlain or treasurer, as unworthy of it. Christ, the Heir of the throne of David, shall supplant all the less worthy stewards who have abused their trust in God's spiritual house, and "shall reign over the house of Jacob," literal and spiritual (Lu 1:32, 33), "for ever," "as a Son over His own house" (Heb 3:2-6). It rests with Christ to open or shut the heavenly palace, deciding who is, and who is not, to be admitted: as He also opens, or shuts, the prison, having the keys of hell (the grave) and death (Re 1:18). The power of the keys was given to Peter and the other apostles, only when, and in so far as, Christ made him and them infallible. Whatever degrees of this power may have been committed to ministers, the supreme power belongs to Christ alone. Thus Peter rightly opened the Gospel door to the Gentiles (Ac 10:1-48; 11:17, 18; especially Ac 14:27, end). But he wrongly tried to shut the door in part again (Ga 2:11-18). Eliakim had "the key of the house of David laid upon his shoulder": Christ, as the antitypical David, Himself has the key of the supreme "government upon His shoulder." His attribute here, as in the former addresses, accords with His promise. Though "the synagogue of Satan," false "Jews" (Re 3:9) try to "shut" the "door" which I "set open before thee"; "no man can shut it" (Re 3:8).
      shutteth--So Vulgate and Syriac Versions read. But the four oldest manuscripts read, "shall shut"; so Coptic Version and ORIGEN.
      and no man openeth--Two oldest manuscripts, B, Aleph, Coptic Version, and ORIGEN read, "shall open." Two oldest manuscripts, A, C, and Vulgate Version support English Version reading.
