Playing the devil's advocate, that was before Jesus Himself ascended to heaven. Couldn't it be the case now, after Jesus's death and resurrection, that there are people in heaven with Jesus now?
No. All the dead are in their graves and all their thoughts have perished so logically no dead person can know they are dead?
The Catholic priest, though a doomed idolater himself, was actually telling the truth about the dead person having to wait for resurrection.
But is that what was really said by a Catholic?
The facts are that through history GOD has slaughtered perhaps a billion people in The Flood, plagues, Egyptians in the Red Sea crossing. These people had one thing in common: they worshipped false gods and idols. The ones who demanded Aaron make the Golden Calf were killed by Moses and then GOD sent a plague to kill many more.
As Armageddon looks likely to kill every Christian and the remnant of the true Jews Jesus will suddenly appear and grab the few Christians and Jews, lift them off Earth, and leave the surviving fighters to be subdued by the angels..
When the battle is over the rapturees will be put down and told the same words as Adam and Eve and Noah heard: Multiply and fill the Earth!
Jesus will then open the graves or recreate any Christian who was burned to dust and give them eternal life on Earth as they died once as believers.
4 And 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.
5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
6 Blessed 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.
For 1000 years the rapturees will have lots of babies to fill the earth while all the resurrected will enjoy living a lovely but celibate life and guiding the children. They died once so will live forever on Earth. The survivors of the nations will also live on earth and have babies while apparently living and believing Jesus and GOD.
However many of these and some of the babies of the rapturees will carry the SEED-DNA of fthe serpent of the Garden of Eden and be tempted to sin.
AT the end of the 1000 years Satan and his fallen angels will be released and go around trying to gather human followers. When he has tempted and gathered all the tainted ones GOD will suddenly send fire to destroy them all except Satan who get a lake of fire to himself.
Then the graves of all the other dead are opened and everyone gets to stand before GOD while He recounts their life and decides if they were deliberately evil or had never heard about being good.
The evil ones are those who had access to Bibles or Christian preachers but rejected their message.
The others who never heard of GOD or Jesus but followed pagan practices out of innocence will get a sympathetic hearing.
