"And I saw the woman, (Babylon), drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration." Revelation 17:6
"And in her, (Babylon), was found the blood of prophets, and of saints, and of all that were slain upon the earth." Revelation 18:24
"For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ. (Am I now seeking the approval of men, or of God? Or am I striving to please men? If I were still trying to please men, I would not be a servant of Christ.:)" Galatians 1:10
"Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets." Mathew 7:12
"A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another." John 13:34-35
"If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen? And this commandment have we from him, That he who loveth God love his brother also." 1 John 4:20-21
"Do not marvel, my brethren, if the world hates you. We know that we have passed from death to life, because we love the brethren. He who does not love his brother abides in death. Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him." 1 John 3:13-15
The key to identifying Babylon is the Blood of the Saints.
Can all of they who have been slain on earth be found in one city, one nation? No.
Is one single false religion responsible for all the deaths upon earth? No.
Can all of the saints and martyrs and prophets be killed in one city, one nation? No.
The people of God have been killed in every nation and in every kingdom at the hands of every self-serving, rebellious ideology. Do the men of these ideologies: the ethicists; the monks; the priests; the holy men do the killing? No. They hire the kings of the earth to do the killing. The kings of the earth enact the edicts and laws according to the desires of these false religious men in order to justify the persecution and killing of God's people. See chapters 3 and 6 of Daniel and the book Esther. The greatest false religion has been that of a false Christianity. Once hired by these erroneous holy men, how do the kings of the earth enforce their edicts and law of persecuting the children of God? They establish armies, domestic and foreign. The kings of the earth and the false prophets work in harmony together to deceive and destroy mankind.
The Antichrist is the agent of Satan the Devil.
The false prophet is the agent of the Antichrist.
The kings of the earth are the agents of the false prophet, false religions.
The soldiers are the agents of the kings.
Soldiers are agents of the Antichrist.
The kings of the earth united are Babylon.
Soldier are agents of Babylon.
A false Christianity is the largest and most influential of the false religions in the world. This false Christianity has been in existence since Constantine commandeered the name Christ, twisting the Christian faith with false beliefs and false doctrines into something that it is not; uniting it with the kingdoms of men, Babylon.
It is this false kingdom that Jesus admonishes his people to come out of, to stop serving the dictates of men who are held captive in fulfilling Satan's goals. Those goals are to persecute the people of God and keep men from the truth and be saved from eternal damnation.. When a Christian serves those who are performing the will of the Antichrist the Christian is performing the will of the Antichrist and will end up persecuting his brothers and sisters in Christ. It is inevitable.
It is impossible for a Christian to ally him/herself with unbelievers and not be forced to compromise aspects of his/her faith at some point in time.
Catholics killing Protestants and Protestants killing Catholics during the Thirty Years' War, the Crusades, the Inquisitions, the Reformation and the Counter-Reformation is completely contrary to the commandments given by Jesus. German Christians killing British Christians during World War Two shows that they ceased walking with God and became a friend of the world in order to avoid persecution from the world. Christians killing Christians during the American civil war demonstrates that they do not love one another and have failed to fulfill the identifying marker of being a true Christian. Killing a brother in Christ for the goals of the Antichrist, for Ceaser, for the world is hate.
It is not that true Christians will never sin, but true Christians will be so allied to each other, so tightly bound to one another, that they will put each other above anything the world asks them to do that would cause harm to a fellow brother or sister in Christ, that would cause harm to Jesus Christ's, body.
