Ellen White clearly identifies the "abomination of desolation" as the Roman army’s banners (idolatrous standards) set up outside of Jerusalem. Here is a direct statement from her writings: "When the idolatrous standards of the Romans should be set up in the holy ground, which extended some furlongs outside the city walls, then the followers of Christ were to find safety in flight. When the warning sign should be seen, those who would escape must make no delay." (The Great Controversy, p. 25.4) She further explains: "Jesus declared to the listening disciples the judgments that were to fall upon apostate Israel... And the Saviour warned His followers: 'When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:) then let them which be in Judea flee into the mountains.' Matthew 24:15, 16; Luke 21:20, 21. When the idolatrous standards of the Romans should be set up in the holy ground, which extended some furlongs outside the city walls, then the followers of Christ were to find safety in flight." (The Great Controversy, p. 25.4; see also Spirit of Prophecy, vol. 4, p. 26.2) These passages confirm that Ellen White taught the "abomination of desolation" was fulfilled when the Roman armies set up their banners in the area surrounding Jerusalem, signaling the time for Christians to flee.
