Not a person, but a state of being. That of being diametrically opposed to the Christ Mind.
We are all the Anti-Christ, in that all(or nearly all) of humanity does not live as Christ, as the awakened Son of God….
The term Antichrist (including one plural form)[2] is found four times in the New Testament, solely in the First and Second Epistle of John.[2] Antichrist is announced as one "who denies the Father and the Son."[2]
Antichrist is translated from the combination of two ancient Greek words ἀντί + Χριστός (anti + Christos). In Greek, Χριστός means "anointed one" and the word Christ derives from it.[10] "Ἀντί" means not only anti in the sense of "against" and "opposite of", but also "in place of".[11][12]
Although the word "antichrist" (Greek antikhristos) is used only in the Epistles of John, the similar word "pseudochrist" (Greek pseudokhristos, meaning "false messiah") is used by Jesus in the Gospels:[14]
For false messiahs and false prophets will appear and produce great signs and omens, to lead astray, if possible, even the elect.
— Matthew 24:24 and Mark 13:22
Another mention of a false prophet in the New Testament is the "antichrist spirit which denies the Son".[9] In the New Testament, the word antichrist (Greek: antikhristos) appears mainly in the Johannine epistles and in the plural, denoting those who deny and/or don't believe in the messianship of Jesus.[9] A similar term, pseudochrist (Greek: pseudokhristos, meaning "false messiah"), is used by Jesus in the Gospels. These terms seem to refer to a category of people rather than a single individual.
