David_Jay » 1 Corinthians 15:29 is not foreign to Judaism. Baptism is based on the Jewish practice of "tevilah." Converts to Judaism would engage in tevilah by immersion ( the Greek word from which "baptism" comes from) in an immersion pool or tub called a "mikveh." The experience symbolized rising from death to a new life in Judaism. But tevilah in a mikveh is also required by Torah if one comes into contact with a dead body. One "washes away death," so to speak, by means of this.
Sorry it's taken so long to get back to you, but my wife's been sick with a summer flu, and it's been like summer here.
The thing about baptism for the dead, yes, I knew about the Jewish rites of baptism and I've seen the places of purification prior to entering the temple. But rites of purification that have to do with immersion have little to do with Christian baptism.
And baptism for the dead has nothing to do with the ritual purification of the dead. The apostle is clearly not speaking about immersing dead bodies because he's speaking about the resurrection of the dead. Christians view the rite of baptism to be redemptive, and an ordinance, not a rite of purification. It's symbolic, with the immersion of man in the likeness of the Messiah's death, and in coming forth out of the tomb in a newness of life as Jesus came forth in the resurrection.
The Lord teaches us through symbolism. In our book of Moses, Adam was taught about the nature of God and the Messiah: “And after many days an angel of the Lord appeared unto Adam, saying: ‘Why dost thou offer sacrifices unto the Lord?’ And Adam said unto him: ‘I know not, save the Lord commanded me.’ And then the angel spake, saying: ‘This thing is asimilitude of the sacrifice of the Only Begotten of the Father, which is full of grace and truth. Wherefore, thou shalt do all that thou doest in thename of the Son, and thou shalt repent and call upon God in the name of the Son forevermore.’” (Moses 6)
And Paul, who like many first century was deeply schooled in Judaism, stated: “Therefore we are buried with him by baptism into death: that like as Christ was raised up from the deadby the glory of the Father, even so we also should walkin newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection.” (Romans 6) Note that he didn't liken it in any way to the purification ceremonies practiced by the Jews of his day. Indeed, John performed his baptisms in a river far from the temple.
Early Christians saw baptism for the dead as a vicarious baptism for someone who has passed on. It has nothing whatsoever to do with the washing of dead bodies. (See Baptism for the Dead).
You also mentioned our agreement with the state of Israel and suggested because of what I told you that we might renege. This is not true. When the days of the Gentiles ends, and the gospel is once more taken to the Jews, it will not be in violation of an existing agreement, but an abrogation of that agreement by the Jewish authorities themselves.
The prophet Zechariah speaks of the return of the Messiah in glory, saying, “And it shall come to pass in that day, that I will seek to destroy all the nations that come against Jerusalem. And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn. In that day shall there be a great mourning in Jerusalem, as the mourning of Hadadrimmon in the valley of Megiddon. And the land shall mourn, every family apart; the family of the house of David apart, and their wives apart; the family of the house of Nathan apart, and their wives apart.” (Zechariah 12:9-12)
According to Christian eschatology, the Jews will, again, in a single day, will come to realize that Jesus is the Christ, and that they had rejected him in the days of his first coming. This is why they will break into mourning across the land. What should have been a joyous occasion will instead be overshadowed with grief. In a modern revelation, the Lord confirms this exegesis when he states, “And then shall the Jews look upon me and say: What are these wounds in thine hands and in thy feet? Then shall they know that I am the Lord; for I will say unto them: These wounds are the wounds with which I was a wounded in the house of my friends. I am he who was lifted up. I am Jesus that was crucified. I am the Son of God. And then shall they weep because of their iniquities; then shall they lament because they persecuted their king. And then shall the a heathen nations be redeemed, and they that knew no law shall have part in the first resurrection; and it shall be tolerable for them.” (D&C 45)
As someone who is himself a Jew, if you were to suddenly discover that, despite your expectations and beliefs, that Jesus is indeed the Messiah, would you not accept him? (And, conversely, if I were to suddenly discover that, despite my convictions, my beliefs in Jesus were in error, would I not want to put them behind me and believe in him no more?) We, indeed, do differ on much as Christians and Jews. Our beliefs in the nature of God, the identity and purpose of the Messiah, our rites and ordinances, how we view the temple, the afterlife, judgment, the return of the prophet Elijah and many other things. You may also wish to read the Book of Mormon to determine the differences between modern Jews and those living in 600 BCE. Those living in the city who were Lehi's primary enemies were convinced they were good people and had done nothing wrong. They were incensed (as were two of Lehi's sons) at the suggestion that they were wicked and would be destroyed because of their wickedness. Even in the wilderness, when Lehi had been told of the city's destruction, his sons refuted to believe it.
