Most Americans don't believe in body's resurrection, putting them at odds with a core teaching of Christianity.

The idea of resurrection wqs an old jewish belief that at the time of Christ was being replaced by the idea of transmigration, that the soul after the death of the body passes into another new body. For some reason that I do not understand, Christians in the state religion of Rome reached back to incorporate the older jewish belief into doctrine.

We Rise Soon after Death

Jesus tells of a poor man Lazarus and his rich neighbor who both died. The rich man ended up in hell, while Lazarus went up to heaven. (Luke 16: 22-24) Both of them came into the next life immediately after death. There was no hint here of a long wait to come back into their bodies, for the rich man's brothers were still alive on earth.

When Jesus was on the cross He promised one of the thieves, "Today you will be with Me in paradise" (Luke 23:43). Jesus did not say, "Just wait twenty centuries or more, and I will fix up your body again."

Since we rise immediately after death, people who have died are in the spiritual world, and they can be seen by those whose spiritual sight is open. For example, when Peter, James and John had their eyes opened to see Jesus in His glory, they also saw Moses and Elijah, who were clearly not in their graves. When Saul went to the witch of En Dor, he spoke with the spirit of Samuel who appeared as an old man (1 Samuel 28: 3-19), and Lazarus found himself in the bosom of Abraham in heaven (Luke 16:22-24). In fact, when Jesus said to the Sadducees that the God of Abraham, Isaac and Jacob is the God of the living, not the dead, the clear implication is that Abramam, Isaac and Jacob had already risen from death into life (Matthew 22:31-32; Mark 12:26-27; Luke 20:37-38). He is "the God of the Living," not "the God of the dead who will centuries later come back to life."

Angels have sometimes appeared to people whose eyes were opened to see them. Very often, the Bible says that these angels are people. For example, we read that three men appeared to Abraham (Genesis 18: 2), and that when Jacob wrestled with an angel he wrestled with a man (Genesis 32: 24). Likewise, the angels were people who appeared to Joshua (Joshua 5: 13-14), Manoah and his wife (Judges 13: 6-11), Ezekiel (Ezekiel 9: 2-3,11; 10: 2-3,6), Daniel (Daniel 9: 21; 10: 5; 12: 6-7), Zechariah (Zechariah 1:8,11), and the women at the sepulcher (Mark 16: 5; Luke 24: 4). The Bible says these angels were people, and clearly none of them were still in the grave.

the body can be resurrected from sin an the soul can be resurrected to heaven

the sadducees (scribes) of Israel during Jesus time did not believe in the resurrection either
but, the pharisees did
they were always bickering over this point

Literal belief in the resurrection is the faith of fools.

you can read what the new testament says about this subject:
Philippians 3
[7] But what things were gain to me, those I counted loss for Christ.
[8] Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,
[9] And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
[10] That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;
[11] If by any means I might attain unto the resurrection of the dead.
[12] Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.
[13] Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
[14] I press toward the mark for the prize of the high calling of God in Christ Jesus.
[15] Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
[16] Nevertheless, whereto we have already attained, let us walk by the same rule, let us mind the same thing.
[17] Brethren, be followers together of me, and mark them which walk so as ye have us for an ensample.
[18] (For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ:
[19] Whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.)
[20] For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:
[21] Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.

a modern day saducee shows up
you can't call any belief foolish

"Resurrection of the dead" in the Nicene Creed sounds more like the soul finding itself alive in heaven after death. "Resurrection of the body" in the later Apostolic Creed is where they made it say the actual physical dead bodies would arise out of their graves and come alive again. Too weird.

it also says in the NT that when we see Jesus, we will be changed in the twinking of an eye
our bodies will be changed to bodies like His incorruptible body which can live eternally with no disease
