The Feast of Trumpets, also known as Yom Teruah or Rosh Hashanah, commemorates the beginning of the fall harvest season and points prophetically to the rapture of the Church. It is the first of three fall feasts that also include Yom Kippur and Tabernacles. According to the document, the blowing of the trumpet on this feast represents the last trumpet call that will sound at Christ's return to catch up believers, as mentioned in 1 Thessalonians and 1 Corinthians. The final, extended trumpet blast also pictures this event. The feast marks the end of the church era and the beginning of God's direct involvement in world affairs during the coming Great Tribulation.
