Here’s Revelation 20:4-6. It’s a resurrection for the millennial kingdom. Those who are resurrected for the millennial kingdom will be on Earth. Later those resurrected people will be on the New Earth.
1. The only way you would view this as heresy is if you’re an amillennialist which denies the earthly millennial kingdom. So either you’re ignorant or confused.
Rev 20:4-6
4And I saw thrones, and they sat upon them, and judgment was given unto them: and
I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received
his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
5But the rest of the dead lived not again until the thousand years were finished. This
is the first resurrection.
6Blessed and holy
is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
2. The Bible says salvation of the soul comes through faith in Christ. Do note that does not include salvation of the resurrected body. The reason the Bible says baptism saves is because it saves something else.
Consider what Paul said in 1 Corinthians:
1 Corinthians 15:29
29Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?
Paul confirmed here that the purpose of baptism is for a resurrection, but individuals must get baptized themself. They can’t be baptized for someone else or someone who has already died.
3. I don’t recall saying what your view of baptism is. I remember making a general statement about people in general believing baptism is unimportant nowadays, which is true. Apparently you took that personally and escalated this to slander. That’s called digging a hole.
