"By the decree enforcing the institution of the papacy in violation of the law of God, our nation will disconnect herself fully from righteousness. When Protestantism shall stretch her hand across the gulf to grasp the hand of the Roman power, when she shall reach over the abyss to clasp hands with spiritualism, when, under the influence of this threefold union, our country shall repudiate every principle of its Constitution as a Protestant and republican government, and shall make provision for the propagation of papal falsehoods and delusions, then we may know that the time has come for the marvelous working of Satan and that the end is near. 5T 451.1"
"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:)"
EGW's description of a threefold union leading to the repudiation of constitutional principles and the propagation of falsehoods can be seen as a parallel to the 'abomination of desolation' in Matthew 24:15, which signifies a time of great apostasy and tribulation. Both passages point to a future event that signals the nearness of the end.
"As the approach of the Roman armies was a sign to the disciples of the impending destruction of Jerusalem, so may this apostasy be a sign to us that the limit of God's forbearance is reached, that the measure of our nation's iniquity is full, and that the angel of mercy is about to take her flight, never to return. The people of God will then be plunged into those scenes of affliction and distress which prophets have described as the time of Jacob's trouble. The cries of the faithful, persecuted ones ascend to heaven. And as the blood of Abel cried from the ground, there are voices also crying to God from martyrs’ graves, from the sepulchers of the sea, from mountain caverns, from convent vaults: “How long, O Lord, holy and true, dost Thou not judge and avenge our blood on them that dwell on the earth?” 5T 451.2"
"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: Let him which is on the housetop not come down to take any thing out of his house: Neither let him which is in the field return back to take his clothes. And woe unto them that are with child, and to them that give suck in those days! But pray ye that your flight be not in the winter, neither on the sabbath day: For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened."
The EGW passage directly alludes to the events described in Matthew 24, drawing a parallel between the destruction of Jerusalem and a future time of tribulation. The reference to the Roman armies as a sign is a clear connection.
"Alas! for that day is great, so that none is like it: it is even the time of Jacob’s trouble; but he shall be saved out of it."
The EGW passage explicitly mentions "the time of Jacob's trouble," which is a direct reference to Jeremiah 30:7. This is more than a thematic parallel; it's a direct allusion.
