Maitreya is not named in Scripture
In Buddhist tradition, Maitreya is understood as a future Buddha who will appear in the world. That belief comes from Buddhist sources, not from the Bible. The Bible does not mention Maitreya, describe him, or connect him with its prophecies about the end times.
So the direct answer is no one can prove from Scripture that Maitreya is the Antichrist. It may feel tempting to match every religious or political figure with a prophecy, especially when a claim sounds spiritual or global. But God has not asked Christians to fill in gaps with guesses.
What does “antichrist” mean?
John wrote that many antichrists had already appeared in his own day. In his letters, an antichrist is especially marked by rejecting the truth about Jesus, including denying the Father and the Son (1 John 2:22). The word does not simply mean any person from another faith, or anyone who receives religious honour.
John's warning is serious, yet it is not an invitation to panic. It helps believers recognise teaching that pulls them away from the real Jesus revealed in the apostles' witness. The clearest test is not whether someone seems impressive, mysterious, or influential. It is what they say and do concerning Christ.
Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
What about the final opponent of Christ?
Paul describes a coming “man of sin” who exalts himself in opposition to God (2 Thessalonians 2:3-4). Many Christians connect this figure with the Antichrist, while others read the passages somewhat differently. Either way, Paul does not provide a name such as Maitreya.
The New Testament's concern is deeper than identifying a headline figure. Deception can involve false worship, proud self-exaltation, and a refusal to receive the love of the truth (2 Thessalonians 2:9-10). Christians are called to hold fast to Christ rather than becoming absorbed in predictions.
Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
Stay watchful without becoming fearful
Jesus warned that false christs and false prophets would arise, so spiritual discernment matters (Matthew 24:24). At the same time, he said that no one knows the day or hour of his return (Matthew 24:36). That leaves room for alertness, humility, and peace.
If you hear someone confidently naming Maitreya, or anyone else, as the Antichrist, ask where Scripture actually says that. Read the relevant passages in context. Then return to the centre of Christian hope: Jesus has overcome the world, and his followers are called to remain faithful to him (John 16:33).
But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
