"Infidel Authors Many think that in order to obtain an education it is necessary to study the productions of writers who teach infidelity, because their works contain some bright gems of thought. But who was the originator of these gems of thought? It was God, and God alone. He is the source of all light. Why should we wade through the mass of error contained in the works of pagans and infidels, for the sake of a few intellectual truths, when all truth is at our command? 8T 306"
"That was the true Light, which lighteth every man that cometh into the world."
Both passages discuss the source of true light and wisdom. John 1:9 identifies Jesus as the true light, while EGW states that God is the source of all light and truth, even in the writings of those who may not acknowledge Him.
"There is a reason why these men sometimes display remarkable wisdom. Satan himself was educated in the heavenly courts, and he has a knowledge of good as well as of evil. He mingles the precious with the vile, and this is what gives him power to deceive. But because Satan has robed himself in garments of heavenly brightness, shall we receive him as an angel of light? The tempter has his agents, educated according to his methods, inspired by his spirit, and adapted to his work. Shall we co-operate with them? Shall we receive the works of his agents as essential to the acquirement of an education? 8T 306.2"
"And no marvel; for Satan himself is transformed into an angel of light."
EGW directly alludes to Satan transforming himself into an angel of light, referencing 2 Corinthians 11:14. The passage expands on the idea of Satan's deceptive nature and his ability to mix truth with error.
"“Who can bring a clean thing out of an unclean? not one.” Job 14:4 . Can we then expect the youth to maintain Christian principles and to develop Christian character while their education is largely influenced by the teachings of pagans, atheists, and infidels? 8T 306.3"
"Who can bring a clean thing out of an unclean? not one."
EGW directly quotes Job 14:4.
