Greetings MaggieMye,
Other scriptures would disagree with this, as they identify the beast/antichrist as a person, an individual. As an example please consider the following:
"But the beast was captured, and with him the false prophet who had performed the signs on his behalf. With these signs he had deluded those who had received the mark of the beast and worshiped his image. The two of them were thrown alive into the fiery lake of burning sulfur." - Rev.19:20
The reference to "the two of them" and they being captured, demonstrates that both the beast and the false prophet as being two individuals and not a system. In fact, right in the scripture that you provided, the antichrist is mentioned as an actual person "you heard that antichrist is coming," as well as those who were types of the antichrist, having the same spirit. In addition, the mention of both the beast and the false prophet being thrown "alive" into the lake of fire would also demonstrate that they are individual beings.
If you read the texts of scripture below, you will come to the correct conclusion that the 'antichrist' is not a person, but rather a "anti-Jesus" way of thinking or of religion...such as the gnostics referred to in Scripture...not by the Name of "gnostic" but by their beliefs. The Antichrist is a SPIRIT...and nowhere in scripture does is say that it will embody a human being.
