John says it has never been seen.
Not true. Read it again.
1Jn 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
"it doesn't yet appear". That doesn't men that is has never been seen. You're conflating thoughts.
John saw Jesus following His death, burial and resurrection. So whatever we will be is not anything like Jesus in His resurrection.
Not true.
Same guy.... John, Same person, Jesus Christ.
Rev 1:11 Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.

Rev 1:16 And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
Rev 1:17 And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last:
Rev 1:18 I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
We know differently. I can review the same information you have and see that what you're claim isn't accurate to the facts of the words recorded.
We will be raised to a spiritual body, That body will not look anything like our physical body.
Not true. Just extrapolated traditions
Even the foundations of the Holy City will have the names (as they are known) of the apostles on them.
Rev 21:14 And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.

Rev 11:16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
There is much more, but you should accept these simple facts.
