Curious as to what precisely makes Full-Preterism considered an non orthodox heresy?

[Ed Parenteau]

That view denies the future Second Coming of Jesus and the Physical resurrection that would happen at that time, so historical has been seen as heretical view

So who cares about the false views of history? It denies what Christ clearly said right along with this dire warning: Rev22:18I warn everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues described in this book, 19and if anyone takes away from the words of the book of this prophecy, God will take away his share in the tree of life and in the holy city, which are described in this book. .

Here are Christ's very last words and all stated in the present tense: So, do what "tradition" has taught you and change them to your hearts delight and make them mean "I am not coming soon". Do you believe Jesus or the creedal traditions? Did Jesus mean what He said or the opposite of what He said?
Revelation 22:7“Behold, I am coming soon. Blessed is the one who keeps the words of prophecy in this book.”...12“Behold, I am coming soon, and My reward is with Me, to give to each one according to what he has done. 13I am the Alpha and the Omega, the First and the Last, the Beginning and the End....” 20He who testifies to these things says, “Yes, I am coming soon.” Amen. Come, Lord Jesus!

It all fits perfectly with Jesus's emphatic promise:
Matthew 24:Truly, I say to you, this generation will not pass away until all these things take place.

If there was the actual Second coming in AD 70, would have had physical resurrection of all saved, and would now be in a paradise earth

 

[Ed Parenteau]

If there was the actual Second coming in AD 70, would have had physical resurrection of all saved, and would now be in a paradise earth

Daniel 12:2
And many who sleep in the dust of the earth will awake, some to everlasting life, but others to shame and everlasting contempt.

The Resurrection Body

35But someone will ask, “How are the dead raised? With what kind of body will they come?” 36You fool! What you sow does not come to life unless it dies. 37And what you sow is not the body that will be, but just a seed, perhaps of wheat or something else. 38But God gives it a body as He has designed, and to each kind of seed He gives its own body.

The resurrection has a destination, and that destination is to eternal life, that is to heaven. So, if the resurrection is to eternal life and it is not the body that goes into the ground as Paul says, then to claim that it is physical is to also claim that heaven is a physical earth like kingdom.
So, where do you get the idea that heaven is a physical earth like kingdom? And what physical body are you talking abouit?
