Summary
Highlights
Four of the seven biblical feasts (Passover, Unleavened Bread, First Fruits, and Pentecost) have already been fulfilled. This leaves three unfulfilled fall feasts: Rosh Hashanah (Feast of Trumpets), Yom Kippur (Day of Atonement), and Sukkot (Tabernacles). Sukkot is known to be fulfilled during the Millennium, meaning only Rosh Hashanah and Yom Kippur remain to be fulfilled.
Rosh Hashanah, also known as the Feast of Trumpets, marks the civil new year. It is unique as it is the only feast that occurs during the New Moon (day of concealment), symbolizing hiddenness. It's also called the day of judgment and the day of the king. The blowing of the Shofar (ram's horn) is central, specifically the “last trumpet,” which is believed to awaken the righteous dead, as detailed in Jewish texts and 1 Corinthians 15:52.
The concept of the 'last trumpet' was understood by first-century Jews and Paul. While the resurrection of the dead at the sound of the last trumpet was known, Paul's revelation in 1 Corinthians 15 concerned the mystery that those alive at the time of this event would also be transformed INSTANTLY, joining the resurrected dead. This event, the Rapture, is theorized to occur at the new moon, the 'day of concealment,' to parallel the moon's hiddenness.
The New Moon (day of concealment) in Judaism, where the moon (believers) reflects light from the sun (God), is seen as a shadow of something to come. This aligns with the idea that the blast from the last trumpet will happen at the New Moon, a day when the righteous dead are raised and concealed with Messiah. Rosh Hashanah is believed to be the starting point of a judgment period, marking the beginning of the 'High Holy Days' and the 'ten days of repentance' leading up to Yom Kippur.
Prophetically, there are seven days between Rosh Hashanah and Yom Kippur, which are seen as 'days of concealment' for believers (Rapture) and 'days of wrath' for those on Earth. During this time, while believers in heaven experience the judgment seat of Christ and the marriage feast, the earth undergoes a period of tribulation (Jacob's trouble). God categorizes people into the completely wicked, the completely righteous (new converts), and intermediates who have until Yom Kippur to decide their fate. This period is when many events from the Book of Revelation are believed to occur.
Paul's statement in 1 Thessalonians 1:10 about being delivered from 'the wrath to come' refers specifically to these 'days of wrath' between Rosh Hashanah and Yom Kippur. First-century Jews would have understood this terminology as the 'days of awe' or 'Jacob's trouble,' indicating that believers would be raptured before this period of intense tribulation.
