I actually read your three posts there. In short, our whole calendar is wrong and filled with references to pagan deities. Furthermore, our holidays are cleverly disguised as something else. Crazy world we live in.
Yep.
Our "holidays" or "holy days" are Satanic counterfeits, and I don't celebrate any of them.
In stark contrast, God's holy days, as given to us in scripture, all foreshadowed or still foreshadow future events.
The Springtime Feasts of Passover, Firstfruits, and Pentecost were all fulfilled on their literal calendar days in that Jesus was crucified on the Feast of Passover, raised from the dead on the Feast of Firstfruits, and the Holy Spirit was poured out on the day of Pentecost.
The Falltime Feasts all point to events which will be fulfilled at Christ's second coming.
The first of said feasts is "The Feast of Trumpets", and it's no coincidence that Christ's coming is heralded by a trumpet blast in the New Testament verses which foretell of the same. In other words, we should fully expect for Christ to return on the literal Feast of Trumpets on the Hebrew calendar which normally coincides with our month of September. Again, as I documented in the post that I linked to and you read, September is really our seventh month ("sept" means seven), and the Feast of Trumpets occurs during the seventh month on the Hebrew calendar.
