This topic is about the “mark of the beast” referred to in the book of Revelation. The mark is given by the second “beast” of Revelation 13, which is also identified by the number “six hundred and sixty-six” (i.e., 666). There is probably more rubbish, complete nonsense, wild speculations, mystical notions, fanciful theories, and fantastical conjurings of man written about this topic than anything else in the entire Bible. Even those who don’t read or believe the Bible or even believe in God seem to know what this mark is, and they are happy to tell you all about it – and it’s almost always wrong, of course. The wildly popular (among both heathens and Christians) teachings and musings are that this mark will be a chip implant, tattoo, or barcode on your forehead or hand; these are complete nonsense. This brings up a good point, which shouldn’t even have to be said, but seems necessary: do not get your Christian doctrine and Bible interpretation from secular sources! You’re in for a world of trouble and deception if you do so, and yet I see it happening all the time.
First, let’s talk about the symbolism and meaning of this passage; only after this is established can we then talk about the possible fulfillments (near and far) of this mark and discuss its applicability to us today.
When you accept Christ, you are born-again of the Holy Spirit who resides in you; this is how you abide in Christ and He in you. Scripture refers to this as being “sealed” with the Holy Spirit. It is symbolically and figuratively described as having a “mark” placed on your forehead, and this mark identifies you as being a child of God. The mark is spiritual – it is not a literal physical mark! King David writes about this as “You have anointed my head with oil” (Psalm 23:5). Revelation 7:3 states that the “bond-servants of [our] God” were “sealed on their foreheads.” Similarly, in the Old Testament period, the Jews were instructed to “bind them [the law] as a sign on your hand and they shall be as frontals on your forehead,” once again using symbolic language for keeping God’s Word “on your heart” (Deuteronomy 6:6-9).
In contrast, for those who reject Christ, the Bible also symbolically speaks about them as having a mark placed on their forehead (or their hand), which signifies that they are following after Satan, the devil, in mind (forehead – heart and mind) and in action/deed (on the hand – doing his works and the deeds of this sinful world). The Bible also refers to this marking as those who have “His [Jesus] name will be on their foreheads” vs. those who have the name of the world (“BABYLON THE GREAT, THE MOTHER OF HARLOTS AND OF THE ABOMINATIONS OF THE EARTH”) written on their foreheads. The symbolism is obvious and the same: followers of Christ or followers of Satan (i.e., this world/man).
Those are the only two families of people on Earth, and everyone who has ever lived will be in one or the other. Correspondingly, there are two marks; you are marked either as:
- Belonging to Christ, or
- Belonging to this world (which is of Satan and those who follow him, including apostate churches and governments of man, i.e., the “beasts” in the book of Revelation)
Furthermore, these marks are constantly being given out during this gospel and church age to those who choose Christ as Lord and those who do not. So, if you are following man and the ways of the world (“for the ways of man lead to death,” Proverbs 14:12), then you have the mark of the beast (who is of Satan, and this world); if you are following Jesus, then you have the mark/anointing of the “Oil of Gladness” (The Holy Spirit) sealing you as a child of God. Once again, that is the symbolism described.
I encourage you to read a couple (or three or four) books on early Christian church history to cure any ignorance of the horrendous persecution that they endured at the hands of the Jews, Romans, and Roman Catholics. It is narcissistic and egocentric to think that all Bible “end-times” prophecy is written to us and applies only to our own future. The book of Revelation would have been immensely helpful to those early Christians, to whom it was expressly written.
Let us now look at the likely specific historical fulfillments of this mark. Contrary to popular opinion today, which by and large thinks that all end-times Bible prophecy (e.g., the book of Revelation) has fulfillment and application only to us who are alive now or in the future, much of the prophecy of the book (but not all) was fulfilled in the early days of the church, when they suffered extreme persecution. The hope that the book of Revelation offers would have been very necessary during the early church.
The mark likely had fulfillment during the early years of the church, where taking the mark meant declaring or proclaiming any man or institution of man (e.g., Roman Caesar, or the Pope) as Lord and God (i.e., worshiping him), thereby denying “the living and true God,” Jesus Christ. That worship was coerced with threats of death, persecution, and economic starvation during the extreme persecution of the early church, first under Rome Pagan (i.e., Caesar) and then under Rome Papal (i.e., the Roman Catholic Church).
In the first case, if a Christian didn’t confess Caesar as Lord and God, they would be burned alive, sent to the arena to be torn apart by lions, or suffer a similar fate. Many Christians refused to take this “mark” of Caesar. Subsequently, under Rome Papal, the Roman Catholic Church was in full power, and if you didn’t confess the Pope as Lord and God, you would be excommunicated (put out of the church), and you would effectively have been cut off from all means of economic livelihood and support (i.e., can’t buy or sell), for the church had an iron grip on nearly all aspects of society. Many faithful Christians refused the “mark” of Papacy.
I value the commentary from biblical scholars not infected with false teachings (such as Dispensational Premillennialism, Postmillennialism, Radical Preterism, the “A.D. 70 Doctrine,” “Realized Eschatology,” etc.), but I also weigh whether they are teaching correct doctrine in other areas as well because, as I’ve indicated, false teachings travel in packs. Reputable commentaries agree that this prophecy likely described (specifically) the persecution of early Christians by the Roman Catholic Church in the centuries after the apostolic/early church age. Note that this was coincident with the rise of Roman Catholicism (the great apostasy mentioned in 2 Thessalonians 2, the “man of sin,” the “lawless one,” i.e., the Pope).
On the second beast of Revelation 13, Matthew Henry writes: 
On the “buying and selling” restriction, he writes:
In summary, the buying and selling restriction likely had an exact literal fulfillment under either the Rome Pagan or Rome Papal persecution of Christians in the early Church. However, this doesn’t change its application, meaning, and purpose to us today, which is: if someone asks you to worship any man, or idol, or any institution of man instead of Christ (or they ask you to deny Christ), simply say no, even in matters of life and death through persecution! You’ll therefore never have to worry about this “mark of the beast.” In effect, if you are worshiping the things of man and this world, you already have the mark of the beast. If you are worshiping Christ “in spirit and in truth,” you do not have the mark of the beast.
And a final note is warranted. Bible prophecies can have both a near and a far fulfillment. So, while this prophecy was likely fulfilled in the persecution of the early Church under Rome Pagan (Caesar) and/or Rome Papal (Roman Catholic Church), Satan (working through the men who choose to follow him) loves to mimic/imitate what is written in Scripture, so there may once again be a time when he tries to recreate what appears to be a far fulfillment of this prophecy in today’s age. But be not deceived.
Also, it is wise to study church history, for one can learn much from those who have gone before us.
