What a fabricated mess. I'm thouroughly impressed. I can see how the pre-trib big guns have misled you well. Why would the last trump be one from a Jewish feast of trumpets, a religion that denies Christ in the first place.
Really? A New Testament that was written exclusively by Jews (with the possible exception of Luke) talking about a Jewish Messiah who is of the tribe of Judah? A religion that totally denies that? No, you have it all wrong.
All of what I stated was developed back in the OT times long before Yeshua arrived. All of what I stated is based on that. Sure, Rabbinic Judaism took a split, but the real Jewish faith remained consistent with the Messiah Yeshua. Belief in Yeshua is the true faith of Abraham, Isaac, and Jacob. And the tradition of Rosh Hashanah / Feast of trumpets that "the last trump" is associated with goes way back. Shavuot/Penatcost is associated with the first trump. Rosh Hashanah/Feast of trumpets is associated with the last trump. And Yom Kippur/Day of Atonement is associated with the great trump. That was developed long before Yeshua, and Paul was intimately familiar with this pattern since he was a high level Pharisee that had been trained in one of the most venerated Jewish schools of theology, the school of Gamliel.
And since the trumpets of Revelation hadn't even been revealed yet, and were not even known by Yeshua yet, there is no way that Paul could have known about them and referred to them. Yes, that is right, I said that Yeshua didn't even know about them when Paul wrote about the last trump. How do I know that? Right from Revelation 1:1.
Revelation 1:1 (NKJV) The Revelation of Jesus Christ,
which God gave Him to show His servants—things which must shortly take place.
And He sent and signified it by His angel to His servant John,
The Revelation was given to Yeshua by the Father and Yeshua gave it to John to give to us. Paul wasn't even in the loop, since Paul had been executed 3-4 decades earlier. So that means the only "last trump" that Paul could be referring to was Rosh Hashanah/Feast of Trumpets. Simple, eh?
What you exhibit is what much to the church has done, divest itself of it's Hebrew roots. Remember, the root feeds us, Romans 11:18. But similar mindsets as yours want to "go your own way" in contradiction to what scripture tells us.
And one thing also stands out.... "The greatest barrier to truth is the presumption that one already has it." The fact that you are not even willing to investigate the matter before commenting on it shows you are in agreement with violating the scripture guidance as expressed in Proverbs 18:13 and Acts 17:11. It would seem you have deeper problems than the topic at hand. You deny plain scripture guidance on proper conduct. By default, that implies that you deny scripture. And if you deny the scripture, you deny the one who gave it. Dangerous ground, buddy.
It is one thing to disagree with a interpretation taken by someone else on such matters after having thoroughly researched it. It is quite another to engage your mouth before you have your brain in gear. Ready, shoot, aim.
