All the earth is Rome!  Well, at least it was to the Empire

In the English language, the words earth, world, or globe are all interchangeable — most of the time.  At times, the word “earth” only means rock and soil as opposed to water. Then there are odd uses as a globe can mean artichoke. The same is true in Greek, oikoumene, refers to a sphere of influence.

There are several different Greek words, oikoumene, get, and kosmos all refer to the earth.

In those days a decree went out from Caesar Augustus that all the world (oikoumene) should be enrolled. Luke 2:1

In Luke, the Greek word is oikoumene, the surface of the earth as opposed to the heaven above. Here it means the people who inhabit the Roman empire and specifically excludes the barbarians outside the Empire from the enrollment tax. 

This distinction is often lost when studying The Revelation. One must carefully consider how the word was used in the first century in Asia Minor. The Revelation is a letter written to them and not us. It was preserved for our benefit but, it is at its core someone else’s mail.

In the book of The Revelation, it becomes clear that once we leave the grand visions of the Throne room, where the whole of the cosmos is nothing but a footstool, the earth is the Roman Earth. 

The book of The Revelation is mostly concerned with the Roman earth or Empire. Everything in the book is Roman. The animal symbol of Rome was a battle horse, the color of the Empire was scarlet, and the capital city of Rome famously sits on seven hills.

Kosmos from which we get the word cosmos or the whole universe is usually translated as ‘world.’ It can mean just the planet but, it can also mean the whole of creation. 

Here are some New Testament references that demonstrate the different uses of the earth or the world. The green indicates ge, and the red indicates kosmos.

Again, the devil took him to a very high mountain, and showed him all the kingdoms of the world and the glory of them; Matt. 4:8

And he said to them, “Go into all the world and preach the gospel to the whole creation. Mark 16:15

They said to the woman, “It is no longer because of your words that we believe, for we have heard for ourselves, and we know that this is indeed the Savior of the world.” John 4:42

. . . and saw the heaven opened, and something descending, like a great sheet, let down by four corners upon the earth. Acts 10:11

Then the seventh angel blew his trumpet, and there were loud voices in heaven, saying, “The kingdom of the world has become the kingdom of our Lord and of his Christ, and he shall reign for ever and ever.” Rev. 11:15 

. . . and all who dwell on earth will worship it, every one whose name has not been written before the foundation of the world in the book of life of the Lamb that was slain. Rev. 13:8 

The beast that you saw was, and is not, and is to ascend from the bottomless pit and go to perdition; and the dwellers on earth whose names have not been written in the book of life from the foundation of the world, will marvel to behold the beast, because it was and is not and is to come. Rev. 17:8
