You are misinterpreting what Paul said in that 1 Cor.15:23-28 passage, and you must include down to verse 28 to get all of it, not just pull out a couple of verses that you want to try to support a doctrine of men like you're doing.
You'd like to think that, wouldn't you? But, point of fact is, verse 28 only brings us full circle and doesn't weigh into the timing or the chronology of things. Verse 28 simply affirms the order of the Trinity...that once Christ has FINISHED his work...that work being delivering the kingdom because he has defeated death...he will be subjected to the Father, and that way God will be all in all. The perfect order of the Trinity established, as it was, as it has been and will be.
Now...you can try and say that has something to say about WHEN Christ returns. WHO he resurrects, WHEN he does it, WHEN death is defeated and WHY that defeat is meaningful THEN...if you want, but I think we both know that it's pointless.
1 Cor 15:23-28
23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
24 Then cometh the end, when He shall have delivered up the kingdom to God, even the Father; when He shall have put down all rule and all authority and power.
Paul is giving a short summary of this subject of 'order' with these 23 & 24 verses. But in the next 25 through 28 verses, he gives more detail of this subject about when that 'end' will be.
And I ALREADY POINTED OUT TO YOU THAT CONDITION FOR THE END THERE IN RED, which you simply chose to IGNORE.
Yeah...maybe it's just me, but your last post didn't seem to mention it at all. Unless you think your reference to the synagogue of Satan was your really obvious link in to this passage, in which case...good job!
But hey...I really, really appreciate the bold, capital font. Shows me you care.
Paul gives MORE INFO ON THAT CONDITION OF CHRIST'S FUTURE REIGN...
25 For He must reign, till He hath put all enemies under His feet.
26 The last enemy that shall be destroyed is death.
27 For He hath put all things under His feet. But when He saith, all things are put under Him, it is manifest that He is excepted, Which did put all things under Him.
28 And when all things shall be subdued unto Him, then shall the Son also Himself be subject unto Him That put all things under Him, that God may be all in all.
KJV
The Father is excepted in that future reign, for only Jesus MUST reign over all His enemies first before the Kingdom can be delivered up to The Father. That is exactly what Apostle Paul is saying there.
It's funny. You say that by missing verse 28 I'm missing the whole point of the passage. But then you seem to focus on it and miss the clear point of everything else. You say that "Jesus MUST reign over all His enemies first before the Kingdom can be delivered up to the Father"?
Swell, great! Here's your problem. Eph 1:20 tell us he's already ruling and reigning over all of them.
Then these verses you skip over tell us that these things that HAVE TO HAPPEN before he can hand over the Kingdom, are sort of neatly wrapped up in a bow and pretty much assumed to have happened (a la Eph 1:20), leaving the ONLY thing left to do (in other words defeat)...death. The real problem you have here, of course, is that two paragraphs later death...you know...the LAST enemy, is, in point of fact....defeated.
Where does that leave you, and all these things that you say have to be done before the Kingdom can be handed over? Reigning over all powers, authority and enemies: check! Defeat death: check! Deliver the Kingdom: check! Be in subjection to the Father: check!
But you are only interested in TWISTING WHAT PAUL SAID THERE! IN FAVOR OF YOUR PET DOCTRINES OF MEN YOU FOLLOW.

Ah, yes...the horrific twisting. Shocking that I should take the verses as they are and shake em out for you, I know. The thing that makes me laugh, is that by writing them out verse by verse as you have, it just makes it more visually obvious how they follow on. This happens, then that happens, then that happens. Ipso facto dude.
