"If the society of a man of impure mind and licentious habits is chosen in preference to that of the virtuous and pure, it is a sure indication that the tastes and inclinations harmonize, that a low level of morals is reached. This level is called by these deceived, infatuated souls, a high and holy affinity of spirit—a spiritual harmony. But the apostle terms it “spiritual wickedness in high places,” against which we are to institute a vigorous warfare. 5T 143.3"
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
EGW directly quotes "spiritual wickedness in high places" from Ephesians 6:12.
"When the deceiver commences his work of deception, he frequently finds dissimilarity of tastes and habits; but by great pretensions to godliness he gains the confidence, and when this is done, his wily, deceptive power is exercised in his own way to carry out his devices. By associating with this dangerous element, women become accustomed to breathe the atmosphere of impurity and almost insensibly become permeated with the same spirit. Their identity is lost; they become the shadow of their seducer. 5T 143.4"
"And no marvel; for Satan himself is transformed into an angel of light."
Both passages discuss deception and the appearance of righteousness masking evil intent. EGW's passage elaborates on the method of deception, while 2 Corinthians 11:14 provides the foundational concept of Satan's disguise.
"For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple."
Both passages address deception through fair speech and the exploitation of the simple. EGW's passage focuses on the loss of identity, while Romans 16:18 highlights the self-serving nature of the deceivers.
