"genuine manifestations, there have been, also, marked exhibitions of supernatural power. The mysterious rapping with which modern spiritualism began was not the result of human trickery or cunning, but was the direct work of evil angels, who thus introduced one of the most successful of soul-destroying delusions. Many will be ensnared through the belief that spiritualism is a merely human imposture; when brought face to face with manifestations which they cannot but regard as supernatural, they will be deceived, and will be led to accept them as the great power of God.

"And no marvel; for Satan himself is transformed into an angel of light."
EGW's statement about spiritualism and supernatural power aligns with the idea that Satan can disguise himself as an angel of light to deceive people. This is a thematic parallel.
"These persons overlook the testimony of the Scriptures concerning the wonders wrought by Satan and his agents. It was by satanic aid that Pharaoh's magicians were enabled to counterfeit the work of God. Paul testifies that before the second advent of Christ there will be similar manifestations of satanic power. The coming of the Lord is to be preceded by “the working of Satan with all power and signs and lying wonders, and with all deceivableness of unrighteousness.” 2 Thessalonians 2:9, 10 . And the apostle John, describing the miracle- working power that will be manifested in the last days, declares: “He doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, and deceiveth them that dwell on the earth by the means of those miracles which he had power to do.” Revelation 13:13, 14 . No mere impostures are here foretold. Men are deceived by the miracles which Satan's agents have power to do, not which they pretend to do. GC 553.2"
"Even him, whose coming is after the working of Satan with all power and signs and lying wonders,"
EGW quotes 2 Thessalonians 2:9 directly, making this an explicit allusion.
"Then Pharaoh also called the wise men and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments."
EGW directly references the account of Pharaoh's magicians and their ability to counterfeit God's work as a parallel to future satanic deceptions. This is a clear allusion to the Exodus passage.
The prince of darkness, who has so long bent the powers of his mastermind to the work of deception, skillfully adapts his temptations to men of all classes and conditions. To persons of culture and refinement he presents spiritualism in its more refined and intellectual aspects, and thus succeeds in drawing many into his snare. The wisdom which spiritualism imparts is that described by the apostle James, which “descendeth not from above, but is earthly, sensual, devilish.” James 3:15 . This, however, the great deceiver conceals when concealment will best suit his purpose. He who could appear clothed with the brightness of the heavenly seraphs before Christ in the wilderness of temptation, comes to men in the most attractive manner as an angel of light. He appeals to the reason by the presentation of elevating themes; he delights the fancy with enrapturing scenes; and he enlists the affections by his eloquent portrayals of love and charity. He excites the imagination to lofty flights, l…
"This wisdom descendeth not from above, but is earthly, sensual, devilish."
Ellen White directly references James 3:15 in this passage.
