"The fact that a few fanatics worked their way into the ranks of Adventists is no more reason to decide that the movement was not of God than was the presence of fanatics and deceivers in the church in Paul's or Luther's day a sufficient excuse for condemning their work. Let the people of God arouse out of sleep and begin in earnest the work of repentance and reformation; let them search the Scriptures to learn the truth as it is in Jesus; let them make an entire consecration to God, and evidence will not be wanting that Satan is still active and vigilant. With all possible deception he will manifest his power, calling to his aid all the fallen angels of his realm. GC 398.1"
"Wherefore by their fruits ye shall know them."
While not a direct quote, the EGW passage uses the principle of judging by fruits to defend the Adventist movement against accusations based on the presence of fanatics, drawing a parallel to similar issues in the early church and during the Reformation.
"summer of 1844, when Adventists were in a state of doubt and perplexity concerning their real position. The preaching of the first angel's message and of the “midnight cry” tended directly to repress fanaticism and dissension. Those who participated in these solemn movements were in harmony; their hearts were filled with love for one another and for Jesus, whom they expected soon to see. The one faith, the one blessed hope, lifted them above the control of any human influence, and proved a shield against the assaults of Satan. GC 398.2"
"One Lord, one faith, one baptism,"
The EGW passage directly references the unity and shared faith of the Adventists, echoing the sentiment of 'one faith' found in Ephesians 4:5. The context of unity and shared belief makes the connection clear.
"“While the bridegroom tarried, they all slumbered and slept. And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him. Then all those virgins arose, and trimmed their lamps.” Matthew 25:5-7 . In the summer of 1844, midway between the time when it had been first thought that the 2300 days would end, and the autumn of the same year, to which it was afterward found that they extended, the message was proclaimed in the very words of Scripture: “Behold, the Bridegroom cometh!” GC 398.3"
"While the bridegroom tarried, they all slumbered and slept. And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him. Then all those virgins arose, and trimmed their lamps."
Ellen White directly references Matthew 25:5-7 in this passage.
"That which led to this movement was the discovery that the decree of Artaxerxes for the restoration of Jerusalem, which formed the starting point for the period of the 2300 days, went into effect in the autumn of the year 457 B.C., and not at the beginning of the year, as had been formerly believed. Reckoning from the autumn of 457, the 2300 years terminate in the autumn of 1844. (See Appendix note for page 329.) GC 398.4"
"Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times."
The EGW passage directly builds upon the prophecy in Daniel 9:25 regarding the decree to restore Jerusalem, using it as the starting point for calculating the 2300-day prophecy. The connection is fundamental to the Adventist understanding of prophecy.
