"that would be produced upon the flock by him and others in teaching the spiritual views. I have often seen the lovely Jesus, that He is a person . I asked Him if His Father was a person and had a form like Himself. Said Jesus, “I am in the express image of My Father's person .” EW 77.1"
"Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;"
EGW directly quotes and references Hebrews 1:3, using the phrase "express image of My Father's person." This is a clear and direct allusion.
"I have often seen that the spiritual view took away all the glory of heaven, and that in many minds the throne of David and the lovely person of Jesus have been burned up in the fire of Spiritualism. I have seen that some who have been deceived and led into this error will be brought out into the light of truth, but it will be almost impossible for them to get entirely rid of the deceptive power of Spiritualism. Such should make thorough work in confessing their errors and leaving them forever. EW 77.2"
"Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much."
Both passages emphasize the importance of confessing errors. EGW specifically mentions confessing errors related to spiritualism, while James 5:16 provides a general principle of confessing faults. The connection is strong and directly related to the principle of confession.
