I'll say again. Has the dead in Christ been raptured to heaven. Has the alive Church that will remain been raptured to heaven. The spring and summer feasts are not fulfilled and will not be fulfilled until the Church is raptured to heaven.
I'll say again. Contrary to popular belief, that you've heard all your life, the Holy Spirit was not given to the Church on Pentecost. Pentecost is 50 days after Passover. But Pentecost does not fully come until 50 days after Pentecost. This is the Feast of New Wine. The Holy Spirit was given to the Church on the Feast of New Wine according to scripture. Read Acts 2 for the full story of the Holy Spirit and the Church.
Acts 2
13 Others mocking said, These men are full of new wine.
14 But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words:
15 For these are not drunken, as ye suppose, seeing it is but the third hour of the day.
As I said. There have been no harvests, so all of the spring and summer feasts have not been fulfilled.
The Feast of Trumpets is for the Jews. That is why there is 144,000 first fruits from the 12 tribes, which are the seed of the woman Israel.
The rapture of the 12 tribes will occur on the Feast of Trumpets at the last trump blown at the celebration, a day of 100 trumpets.
Then there is the Day of Atonement which will happen after the wrath of God which ends at the 7th trumpet. Then there is Tabernacles. And you are correct that that they won't happen in the same year.
