Revelation 18:4-6

And I heard another voice from heaven Probably the voice of Christ, graciously warning his people of their danger of being infected by the prevailing corruptions of the mystical Babylon, and, in consequence thereof, of being involved in her ruin; saying, Come out of her, my people Immediately forsake the communion of so corrupt a church; that ye be not partakers of her sins Which you surely will be if you do not separate yourselves from her; and that ye receive not of her plagues That ye share not in that guilt which would render you liable to all the plagues and judgments with which she shall assuredly be punished. But, as Bishop Newton observes, “was there any such necessity of forsaking the Church of Rome in the days of Alaric or Totilas, before she had degenerated again into idolatry? Or, what were then her notorious crimes, deserving of such exemplary punishment, unless Rome Christian was to suffer for the sins of Rome pagan?” What a remarkable providence it was that this book of the Revelation was printed in the midst of Spain, in the Great Polyglot Bible, before the Reformation! Else how much easier had it been for the Papists to reject the whole book, than it is to evade these striking parts of it! For her sins have reached unto heaven When sins are ripe for judgment, they are said to reach unto heaven, or to come up before the face of Jehovah. So the angels speak who were sent to punish the sins of Sodom, Genesis 19:13, We will destroy this place, because the cry of them is waxed great before the face of the Lord. Thus God said to Jonah, Cry against Nineveh, for their wickedness is come up before me: and St. James uses a like expression concerning oppressors, The cries of them which have reaped have entered into the ears of the Lord of Sabaoth. It seems to be an elegant allusion to the methods of justice in human courts, when criminals are actually prosecuted, and their crimes are brought to light before the court of judgment. Reward her God speaks to the executioners of his vengeance; even as she hath rewarded Others, in particular the saints of God; and double unto her double This, according to the Hebrew idiom, implies only a full retaliation; according to her works The injuries and evils with which she has oppressed the faithful servants of God. In the cup which she hath filled, fill to her double Let her suffer whatever the laws of justice have made the punishment of such great offences. By the laws of the Jewish government some offences were punished by retaliation, or by inflicting on the offender that evil which he had injuriously done to his neighbour. It was therefore enacted by the Jewish law, that life should be given for life, eye for eye, tooth for tooth, hand for hand, foot for foot, Exodus 21:23, &c. In other cases of damage it was enacted that the offender should pay double damages. Thus, in the case of theft, the law required the thief to restore double, (Exodus 22:4,) it being just that the thief should suffer for his offence, as well as make full restitution for the damage he had done. In allusion to these laws of the Jewish government, divine justice is represented as punishing Rome for her idolatry and persecution, by inflicting upon her, as an offender, such pains and penalties as the laws of equity direct, where injuries are so highly criminal.
