Let’s understand why ― not in order to disparage other religions, but rather to clarify the Jewish position.
Jews do not accept Jesus as the messiah because:
1 Jesus did not fulfill the messianic prophecies.
2 Jesus did not embody the personal qualifications of the Messiah.
3 Biblical verses “referring” to Jesus are mistranslations.
4 Jewish belief is based on national revelation.
But first, some background: What exactly is the Messiah?
The word “Messiah” is an English rendering of the Hebrew word Mashiach, which means “anointed.” It usually refers to a person initiated into God’s service by being anointed with oil. (Exodus 29:7, 1-Kings 1:39, 2-Kings 9:3)
1 Jesus Did Not Fulfill the Messianic Prophecies
What is the Messiah supposed to accomplish? One of the central themes of biblical prophecy is the promise of a future age of perfection characterized by universal peace and recognition of God. (Isaiah 2:1-4, 32:15-18, 60:15-18; Zephaniah 3:9; Hosea 2:20-22; Amos 9:13-15; Micah 4:1-4; Zechariah 8:23, 14:9; Jeremiah 31:33-34)
Specifically, the Bible says he will:
1 Build the Third Temple (Ezekiel 37:26-28).
2 Gather all Jews back to the Land of Israel (Isaiah 43:5-6).
3 Usher in an era of world peace, and end all hatred, oppression, suffering and disease. As it says: “Nation shall not lift up sword against nation, neither shall man learn war anymore.” (Isaiah 2:4)
4 Spread universal knowledge of the God of Israel, which will unite humanity as one. As it says: “God will be King over all the world ― on that day, God will be One and His Name will be One” (Zechariah 14:9).
If an individual fails to fulfill even one of these conditions, then he cannot be the Messiah.
Because no one has ever fulfilled the Bible’s description of this future King, Jews still await the coming of the Messiah. All past Messianic claimants, including Jesus of Nazareth, Bar Cochba and Shabbtai Tzvi have been rejected.
Christians counter that Jesus will fulfill these in the Second Coming. Jewish sources show that the Messiah will fulfill the prophecies outright; in the Bible no concept of a second coming exists.
2) Jesus Did Not Embody the Personal Qualifications of Messiah
1 Messiah as Prophet
The Messiah will become the greatest prophet in history, second only to Moses. (Targum – Isaiah 11:2; Maimonides – Yad Teshuva 9:2)
Prophecy can only exist in Israel when the land is inhabited by a majority of world Jewry, a situation which has not existed since 300 BCE. During the time of Ezra, when the majority of Jews remained in Babylon, prophecy ended upon the death of the last prophets ― Haggai, Zechariah and Malachi.
Jesus appeared on the scene approximately 350 years after prophecy had ended, and thus could not be a prophet.
1 Descendent of David
Many prophetic passages speak of a descendant of King David who will rule Israel during the age of perfection. (Isaiah 11:1-9; Jeremiah 23:5-6, 30:7-10, 33:14-16; Ezekiel 34:11-31, 37:21-28; Hosea 3:4-5)
The Messiah must be descended on his father’s side from King David (see Genesis 49:10, Isaiah 11:1, Jeremiah 23:5, 33:17; Ezekiel 34:23-24). According to the Christian claim that Jesus was the product of a virgin birth, he had no father ― and thus could not have possibly fulfilled the messianic requirement of being descended on his father’s side from King David. (1)
According to Jewish sources, the Messiah will be born of human parents and possess normal physical attributes like other people. He will not be a demi-god, (2) nor will he possess supernatural qualities.
1 Torah Observance
The Messiah will lead the Jewish people to full Torah observance. The Torah states that all mitzvot remain binding forever, and anyone coming to change the Torah is immediately identified as a false prophet. (Deut. 13:1-4)
Throughout the New Testament, Jesus contradicts the Torah and states that its commandments are no longer applicable. For example, John 9:14 records that Jesus made a paste in violation of Shabbat, which caused the Pharisees to say (verse 16), “He does not observe Shabbat!”
3) Mistranslated Verses “Referring” to Jesus
Biblical verses can only be understood by studying the original Hebrew text ― which reveals many discrepancies in the Christian translation.
1 Virgin Birth
The Christian idea of a virgin birth is derived from the verse in Isaiah 7:14 describing an “alma” as giving birth. The word “alma” has always meant a young woman, but Christian theologians came centuries later and translated it as “virgin.” This accords Jesus’ birth with the first century pagan idea of mortals being impregnated by gods.
1 Suffering Servant
Christianity claims that Isaiah chapter 53 refers to Jesus, as the “suffering servant.”
In actuality, Isaiah 53 directly follows the theme of chapter 52, describing the exile and redemption of the Jewish people. The prophecies are written in the singular form because the Jews (“Israel”) are regarded as one unit. Throughout Jewish scripture, Israel is repeatedly called, in the singular, the “Servant of God” (see Isaiah 43:8). In fact, Isaiah states no less than 11 times in the chapters prior to 53 that the Servant of God is Israel.
When read correctly, Isaiah 53 clearly [and ironically] refers to the Jewish people being “bruised, crushed and as sheep brought to slaughter” at the hands of the nations of the world. These descriptions are used throughout Jewish scripture to graphically describe the suffering of the Jewish people (see Psalm 44).
Isaiah 53 concludes that when the Jewish people are redeemed, the nations will recognize and accept responsibility for the inordinate suffering and death of the Jews.
