I have an issue with this idea. The rapture is for the church, not for Israel (as a whole). Why would Jesus fulfill a Jewish feast with the removal of the church? There are many references to trumpets in the Bible, so that can't be a good enough reason. Moses made two trumpets. He used the one during the time of the exodus and wandering in the desert. What if the other is the last trump? The one that calls the church home. (Just a thought.)
I tend the think the Feast of Trumpets will NOT be when Jesus comes for the church because it seems to me He will fulfill that feast when he returns to earth in the second coming, specifically for the redemption of the Jewish nation.
But couldn't Daniel's 70th week start with the Feast of Trumpets? Didn't all of the other weeks end on Shemitah years? So maybe not the Day, but a day of interest, none the less.
I'm circling back to this again because I just started reading "The Footsteps of the Messiah" and Arnold F. believes the rapture will happen at the Feast of Trumpets. I just don't think so.
The first 4 feasts were fulfilled in succession IN THE SAME YEAR. Why would the last 3 feasts not also be fulfilled in succession in the same year? Atonement and Tabernacles will. How does it make sense that the Feast of Trumpets will be carved out by itself 7+ years ahead?
AND, the purpose of the Feast of Trumpets is a convocation for repentance. The church has already repented, so why does it make sense to call us to repentance in order to fulfill this feast? To me, it doesn't square.
I think the Feast of Trumpets will occur 9 days before the Day of Atonement at the Second Coming. End of rant! 😋😂
I definitely see the linkage between the first trump in Exodus, and the last trump being for the Rapture. Both were gathering events for two specific peoples (Israel and the Church). Like you, I don't necessarily think this needs to fall on the Feast of Trumpets (or any Jewish holiday-even Pentecost). It could, if in keeping with Christ's own personal fulfillment of prophetic events along the Jewish Feast annual timeline, but we just don't know. I absolutely think its soon though.
