Revelation 18:4

(4) Voice from heaven . . .—Read, Voice out of heaven, saying, Come forth out of her, my people, that ye partake not in her sins, and that of her plagues ye receive not. The voice is not said to be that of another angel. It is not necessary to say whose voice it is; that it is a voice of divine love giving warning is enough. The coming forth is not to be understood of a bodily exodus from Rome. It is rather the warning which is so needful in every corrupt state of society, to have no fellowship with the unfruitful works of darkness; to practise that separation from the spirit of the world which is essential lest we should be entangled in the meshes of its sinful habits. This duty of separation may sometimes lead to a literal exodus, and even under the pressure of overwhelming necessity to secession from a world-corrupted church; but the jeopardy lies in attachment to the world-spirit (1 John 2:15). The parallel warnings in Jeremiah 51:6; Jeremiah 51:45, and Zechariah 2:6-7, should be read; but the story of Lot in Sodom best illustrates the spirit of the passage (Genesis 19:0), for it is participation in sin which is to be primarily guarded against.
