We are changed---both the resurrected dead in Christ and those who remain alive when he returns.
NO. There is absolutely no promise of a change given to
those who have not yet physically died when Christ returns. You are inventing this in contradiction to the rule that you yourself believe that all of Adam's progeny are to physically die as a result of the fall.
That "change" to the incorruptible and the immortal is for
the saints who have died, whose physical bodies are sleeping in the grave. NONE of those dead saints remain in the grave at Christ's return. ALL of the dead saints are changed in a moment, and in the twinkling of an eye.
Do they die when he returns and then are resurrected? When is it that they die?
YES. With Christ's future return, the saints die at that return, and are resurrected that same day when their dead bodies are then changed into the incorruptible and immortal state. Whether saint or sinner,
nobody while in this mortal body can look upon that level of holiness and live through the experience.
It does not say they all were. So at the very least it is not equal to the resurrection at Christ's return. It could relate directly to the coming kingdom.
What are you talking about?
Every one of those Matthew 27:52-53 saints came out of their graves at Jerusalem on the same day as Christ's resurrection. But you are right that this event was not equal to the next resurrection event at Christ's return, because that was only a
"remnant of the dead" which participated in that "First resurrection" in AD 33 (Rev. 20:5). They along with Christ were the "FIRST-fruits" to be raised out of the grave: all 144,000 of those resurrected "First-fruits".
Hymenaeus and Philetus are mentioned in 2 Timothy 2:17 and what they were teaching may have been a form of Gnosticism or may have been a combination of things deadly to the gospel. So you begin you assertions with false assertions.
"False assertions"?? Let me quote. "...Hymenaeus and Philetus; Who concerning the truth have erred, saying that
the resurrection is past already; and overthrow the faith of some." This was
not Gnosticism which denies a bodily resurrection altogether. These men were teaching that the expected resurrection was over and done with by then, and that there would not be another resurrection for the saints who had died after that resurrection event of Christ and the Matthew 27:52-53 saints had taken place. This was discouraging for those first-century saints who had seen their own believing kindred die since Christ's ascension, and who were thinking that these dead loved ones would remain forever in the grave, and had "missed the boat", so to speak.
Where is your evidence of this? It would be just grand if people would attach evidence along with these blanket statements of fact.
I just gave it to you already, as found in Ephesians 4:8-12. The Matthew 27:52-53 saints (that "multitude of captives" which the ascended Christ led out of the grave that day) were given as "gifts to men". It was incumbent upon every high priest
to offer gifts and sacrifices (Heb. 8:3). At His resurrection-day ascension, the newly-anointed Great High Priest Christ Jesus did this when He offered these
"gifts to men" (the resurrected "multitude of captives" He had led out of the grave). These all served in the early church for its edification, and for perfecting the saints for the work of the ministry.
Also Roman 8:23 in which Paul wrote that the church had the "First-fruits" still among them at that time. Those "First-fruits" numbered 144,000 (as in Rev. 14:4), and they did not ascend with Christ in Acts 1. They "remained" on the earth to serve in the early church as the "alive" ones who "remained" until Christ's return, as Paul described in 1 Thess. 4. No man was able to enter heaven's temple until the 7 plagues were finished (Rev. 15:8), so we know that no resurrected members of humanity were allowed entrance until then - including Enoch, Moses, or Elijah, as some presume.
