No more important question can be asked in connexion with the interpretation of the Apocalypse. The thought of Babylon is evidently one by which the writer is moved to a greater than ordinary degree. Twice already have we had premonitions of her doom, and that in language which shows how deeply it was felt.[466] In the passage before us he is awed by the contemplation of her splendour and her guilt. And in chap. xviii. he describes the lamentation of the world over her fate in language of almost unparalleled sublimity and pathos. What is Babylon? We must make up our minds upon the point, or the effort to interpret one of the most important parts of the Revelation of St. John can result in nothing but defeat. Very various opinions have been entertained as to the meaning of Babylon, of which the most famous are that the word is a name for papal Rome, pagan Rome, or a great world-city of the future which shall stand to the whole earth in a relation similar to that occupied by Rome towards the world of its day. These opinions cannot be discussed here; and no more can be attempted than to show, with as much brevity as possible, that by Babylon is to be understood the degenerate Church, or that principle of degenerate religion which allies itself with the world, and more than all else brings dishonour upon the name and the cause of Christ. (1) Babylon is the representative of religious, not civil, degeneracy and wickedness. She is a harlot, and her name is associated with the most reckless and unrestrained fornication. But fornication and adultery are throughout the Old Testament the emblem of religious degeneracy, and not of civil misrule. In numerous passages familiar to every reader of Scripture both terms are employed to describe the departure of Israel from the worship of Jehovah and a holy life to the worship of idols and the degrading sensuality by which such worship was everywhere accompanied. Nor ought we to imagine that adultery, not fornication, is the most suitable expression for religious degeneracy. In some important respects the latter is the more suitable of the two. It brings out more strongly the ideas of playing the harlot with "many lovers"[467] and of sinning for "hire."[468] In this sense then it seems proper to understand the charge of fornication brought in so many passages of the Apocalypse against Babylon. Not in their civil, but in their religious, aspect have the kings of the earth committed fornication with her, and they that dwell on the earth been made drunk with the wine of her fornication. Her sin has been that of leading men astray from the worship of the true God, and of substituting for the purity and unworldliness of Christian living the irreligious and worldly spirit of the "earth." To this it may be added that, had Babylon not been the symbol of religious declension, she could hardly have borne upon her forehead the term MYSTERY. St. John could not
