In this epistles, John the apostle mentions a term that has become synonymous with the archenemy of Christ or the Messiah and Christians everywhere. It is Antichrist. This word’s meaning is self-evident, but, by John’s own definition, let’s now discover who really fits the strictest definition of Antichrist.

The first place John mentions this term is in the second chapter of his first epistle.

Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour. (1 John 2:18)

The prophetic apostles then goes on to make two further references to this arch-villain of the Messiah and his disciples.

…and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world. (1 John 4:3)

For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist. (2 John 1:7)

How does John define the spirit of antichrist? From 1 John 2:18–19, 22; 4:3; 2 John 7 we learn the following:

• The antichrist spirit was prophesied to come on the scenes. Presumably, this specific spirit could not emerge until the Messiah had come.
• The Antichrist or the spirit thereof pretends to the Messiah or the Anointed One from heaven and deceives people into believing this lie.
• Antichrist and all spirits of antichrist, in the most literal sense, emerged of the first century apostolic faith of the Jewish Christian community or, by possible extension, its direct successors. 
• The spirit of antichrist denies that Yeshua is the Messiah (Savior and Redeemer of man).
• The satanic spirit denies that Yeshua is part of the “Godhead”. 
• Next, it denies that Yeshua is is deity and is the Son of Elohim.
• Finally, it denies the incarnation of Yeshua. 

This then is how the Bible defines the spirit of antichrist.

Other biblical references that many Christians scholars believe allude to this end times Antichrist figure include:

• The Beast (Rev 13:4)
• The abomination that causes desolation (Matt 24:15)
• The desolator (Dan 9:27)
• The man of sin (or lawlessness), the son of perdition (2 Thess 2:3)
• The little horn (Dan 7:8)
• The Assyrian (Mic 5:5; Isa 10:5; 14:25)

What should be our reaction when we encounter this demonic spirit of antichrist? The wise counsel of John in his second epistle sums up our firm conviction on this matter.

Whoever transgresses and does not abide in the doctrine of Messiah does not have Elohim. He who abides in the doctrine of Messiah has both the Father and the Son. If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him; for he who greets him shares in his evil deeds. (2 John 9–11)

What additionally can we learn about the person of the Antichrist and the spirit of antichrist from the four passages where antichrist is mentioned in John’s epistles?

From 1 John 2:18–19, 22; 4:3; 2 John 7 we learn that the Antichrist and all spirits of antichrist have come out of the first century apostolic faith of the Jewish Christian community. In the strictest sense, this eliminates some of the world’s largest religions (e.g., Hinduism, Buddhism) as being contenders for the end times religious system of the Antichrist. That leaves paganized mainstream Christianity and Islam. From John’s writings, we also learn that the spirit of antichrist denies that Yeshua is the Messiah (Savior and Redeemer of man), denies that Yeshua is part of the “Godhead,” is deity and is the Son of Elohim, and denies the incarnation of Yeshua. This rules out mainstream Christianity, even in its paganized or somewhat apostate form. Of the existing major world religions extant on earth today, only Islam fits the strictest biblical definition of Antichrist and religion thereof. 

Yes, it is true that Islam did not yet exist in John’s day. John died in the 90s A.D., and Muhammad, the founder of Islam, was not born until A.D. 570. However, Islam did not spontaneously combust out of a religious vacuum. If one reads the Koran, one will discover that the tenets of Islam are pulled from several already existing religious systems of the day including Judaism, Christianity, the moon worshipping religion of Muhammad’s own tribal religious system, as well as from the Greek philosophers including that of dualism and gnosticism. When one reads the entire Koran, it is becomes evident that Islam is a mongrelized, jumbled mixture of a various religious threads and traditions.

This then begs a relevant question: To what religious system was John specifically referring when he penned his first and second epistles probably late in his life in the A.D. 90s? What religious ideology was in existence in his day that had broken off of early Christianity and was proclaiming a false Messiah among other things? This most likely would have been the religion of gnosticism that Paul was already combatting in his epistle to the Colossians, and which rose to prominence under Marcion (the heretic) of Sinope (A.D. 85–160), who came to prominence in the early to mid-second century A.D. Eventually, the early church fathers branded gnosticism as a heresy and Marcion a heretic for denying the bodily manifestation of Yeshua the Messiah. However, later on, Muhammad would pick up and proclaim some elements of Gnostic heresy and it would be enshrined in the Koran. Thus, modern Islam is the descendant of this antichrist doctrine.

Now having established which major religious system fits the strictest definition of antichrist as John defines it, we cannot overlook the fact that John also states, “it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come….” While in the end times there may be one Antichrist figure that personifies a larger philosophy of rebellion against the YHVH Elohim and his divine Truth as revealed in his word, the Bible, John leaves the door open for there to be many other iterations of the antichrist spirit as well. 

In the loosest sense, anyone, any philosophy, any religious system or anything else that opposes Yeshua the Messiah or Jesus Christ and the Word and Truth of the Bible is of the spirit of Antichrist. This would include anyone or anything that aligns itself with Islam and takes a stand against the followers of Yeshua or those who teach the Word of Elohim. Let’s be frank here. This eventually includes almost the entire world! 

Moreover, there are strains of the spirit of antichrist in modern religious Judaism, and even mainstream Christianity. That is why YHVH pleads if not commands his people to come out of Babylon (Rev 18:4).

To be sure, the spirit of antichrist exists in all of the false religions of the world as well such socioeconomic systems as Marxism and all of its ungodly substrates. 

Eventually, the nascence of the spirit of antichrist goes back to Satan the serpent in the Garden of Eden, when he deceived the first humans into joining him in his preexisting rebellion against the commands or the word of Elohim. 

Ultimately, the evil spirit of antichrist, which is rebellion against YHVH’s Torah-word, has spread its destructive cancerous tentacles globally and now infest everyone and everything. In a word, the spirit of antichrist is nothing more than sin, which is rebellion against and the violation of YHVH’s Torah-law or commandments (1 John 3:4). Only through a relationship with Yeshua the Messiah, who came as Elohim in the flesh as the Son of YHVH Elohim, can sinful and rebellious man be redeemed and set free from the grip of the spirit of antichrist. Those who remain under the control of this satanic spirit will die in their sins, while those who repent and turn to Yeshua and receive him not merely as their Savior, but as their Lord and Master and love him by conforming their lives to his Torah-word will experience eternal life and inclusion in the kingdom of heaven as adopted sons and daughters into the family of Elohim.
