It was this theory of sanctification which Sister G received of Elder K, and which she tried to follow out, that carried her into that dreadful fanaticism. Elder K has bewildered and confused many minds with this theory of sanctification. All who embrace it lose to a great extent their interest in and love for the third angel's message. This view of sanctification is a very pretty-looking theory. It whitewashes over poor souls who are in darkness, error, and pride. It gives them an appearance of being good Christians, and of possessing holiness, when their hearts are corrupt. It is a peace-and-safety theory, which does not bring to light evil and reprove and rebuke wrong. It heals the hurt of the daughter of God's people slightly, crying: Peace, peace, when there is no peace. Men and women of corrupt hearts throw around them the garb of sanctification, and are looked upon as examples to the flock, when they are Satan's agents, used by him to allure and deceive honest souls into a bypat…
"Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men’s bones, and of all uncleanness."
The 'whited sepulchres' in Matthew 23:27 directly parallels EGW's description of the theory of sanctification as 'whitewashing over poor souls' and giving a false appearance of holiness. This is a strong thematic connection.
"Having a form of godliness, but denying the power thereof: from such turn away."
Both passages warn against those who have a superficial appearance of godliness but lack genuine spiritual power. The 'form of godliness' in 2 Timothy is similar to the 'appearance of being good Christians' described by EGW.
"Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves."
Both passages warn against those who appear righteous but are inwardly corrupt and deceptive. The 'sheep's clothing' is analogous to the 'garb of sanctification' that hides their true nature.
"They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate."
Both passages address the hypocrisy of professing faith while denying it through actions. EGW describes those who appear holy but are corrupt, while Titus speaks of those who profess to know God but deny Him in their works.
"And no marvel; for Satan himself is transformed into an angel of light."
Both passages discuss deception and the appearance of good masking evil. EGW describes Satan's agents appearing as examples, while 2 Corinthians speaks of Satan transforming into an angel of light.
