The Preterist denies that Christ exist in heaven still in his glorified body, in which Philippians 3:21 states that Christ in heaven has, they will argue its not a physical body yet every scriptures tells us a body is always "physical", and there is not one scriptures that will teach a body can be just like a spirit, immaterial. They will claim Christ shed his body after he ascended or that it changed to "spirit" but they can not produce one scripture that says so. An apologetic will answer why he has a body in heaven from scriptures and what is it's purpose.` It will explain theologically why Jesus became a man and remains a man for all eternity. (Jesus is fully God and Fully man) The reason the Preterist must deny Christ is still physical is because IF he had returned in AD 70, then a physical body would have been seen, but since they know there is no evidence of Christ being seen, yet they claim he came, so it had to be an "invisible" appearing in the spiritual realm which means Christ can not have a physical body.. This is how they force scripture to fit their paradigm and why we must provide a sound answer. Incorrect doctrine leads to confusion which, as Paul states, causing problems with peoples faith. Contradictions destroys a person ability to trust that scriptures are true for if it can be proven scriptures are wrong in any area then how we can we trust anything in our bible.
