Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.
Is it your opinion that the resurrection of the dead took place in 312 AD as well?
14 For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus. 15 For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep. 16 For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. 17 Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. 1 Thessalonians 4:14-17
The above scripture teaches us that when The Lord Jesus returns, the dead in Christ will rise also, and from that point on we shall all be with the Lord.
Are saying that the resurrection is past?
2 Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is. 3 And everyone who has this hope in Him purifies himself, just as He is pure. 1 John 3:2
Are you saying that you are now at this moment wearing a glorified body that will never die.
34 And Jesus answered and said to them, "The sons of this age marry and are given in marriage. 35 But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage; 36 nor can they die anymore, for they are equal to the angels and are sons of God, being sons of the resurrection. Luke 20:34-36
Are you saying, somehow, that people no longer marry or are given in marriage?
It seems that The Lord Jesus and the apostle Paul taught a completely different Gospel than the one you teach.
Furthermore Paul taught us that those who teach the resurrection is past teach a message that is like cancer, a disease that spreads and overthrows the faith of God's people.
16 But shun profane and idle babblings, for they will increase to more ungodliness. 17 And their message will spread like cancer. Hymenaeus and Philetus are of this sort, 18 who have strayed concerning the truth, saying that the resurrection is already past; and they overthrow the faith of some.

6 I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel, 7 which is not another; but there are some who trouble you and want to pervert the gospel of Christ. 8 But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. 9 As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed. Galatians 1:6-9
You are treading on extremely dangerous ground.
I encourage you to turn away from this perverted teaching.
