The antichrist is not merely one individual person or entity, for the Bible says that there are “many antichrists.” (1 John 2:​18) Rather, the term “antichrist,” which comes from a Greek word meaning “against (or instead of) Christ,” refers to anyone who does the following:

•   Denies that Jesus is the Christ (Messiah) or denies that he is the Son of God.​—1 John 2:​22.

•   Opposes the Christ, God’s Anointed One.​—Psalm 2:​1, 2; Luke 11:23.

•   Pretends to be the Christ.​—Matthew 24:24.

•   Persecutes the followers of Christ, since Jesus views what is done to them as being done to him.​—Acts 9:5.

•   Falsely claims to be a Christian while practicing lawlessness or deception.​—Matthew 7:​22, 23; 2 Corinthians 11:13.

 Besides speaking of individuals who take such actions as being antichrists, the Bible also refers to them collectively as “the antichrist.” (2 John 7) The antichrist first appeared in the time of the apostles and has been active ever since. Bible prophecy foretold just such a development.​—1 John 4:3.

•   They promote false ideas related to Jesus. (Matthew 24:​9, 11) For example, those who teach the Trinity or that Jesus is Almighty God actually oppose the teachings of Jesus, who said: “The Father is greater than I am.”​—John 14:28.

•   Antichrists reject what Jesus said about how God’s Kingdom operates. For instance, some religious leaders say that Christ works through human governments. Yet, this teaching contradicts Jesus, who said: “My Kingdom is no part of this world.”​—John 18:36.

•   They say that Jesus is their Lord, but they do not obey his commands, including the one to preach the good news of the Kingdom.​—Matthew 28:19, 20; Luke 6:​46; Acts 10:42.
