What religion is the spirit of antichrist?

What religious system on earth today fits the biblical definition of the spirit of antichrist? There is only one you will see from the brief study below.

1 John 2:18, The Antichrist. Other biblical references that many Christians scholars believe allude to the end times Antichrist figure include:

Many antichrists. How does John define the spirit of antichrist? 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. From these passages 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,” that he is deity and is the Son of Elohim, and denies the incarnation of Yeshua. This is how the Bible defines the spirit of antichrist.

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. This eliminates some of the world’s large religions (e.g., Hinduism, Buddhism) as being contenders for the end times religious system of the Antichrist. That leaves pagan Christianity and Islam. From these passages 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. Only Islam adheres to these beliefs.

The only religion on earth today that strictly fits the biblical definition of the religion of antichrist is Islam.
