"In the night season I was a witness to the performance that was carried on on the school grounds. The students who engaged in the grotesque mimicry that was seen, acted out the mind of the enemy, some in a very unbecoming manner. A view of things was presented before me in which the students were playing games of tennis and cricket. Then I was given instruction regarding the character of these amusements. They were presented to me as a species of idolatry, like the idols of the nations. CT 350.1"
"But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils."
EGW equates certain amusements (tennis, cricket) to idolatry, linking them to the 'idols of the nations.' This thematically parallels 1 Corinthians 10:20, which states that sacrifices to idols are actually sacrifices to demons. While not a direct quote, the underlying principle of associating certain practices with demonic influence is present in both passages.
"There were more than visible spectators on the ground. Satan and his angels were there, making impressions on human minds. Angels of God, who minister to those who shall be heirs of salvation, were also present, not to approve, but to disapprove. They were ashamed that such an exhibition should be given by the professed children of God. The forces of the enemy gained a decided victory, and God was dishonored. He who gave His life to refine, ennoble, and sanctify human beings was grieved at the performance. CT 350.2"
"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."
Both passages discuss spiritual warfare and the presence of both good and evil spiritual forces influencing human actions. EGW's passage elaborates on the unseen battle described in Ephesians.
"Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?"
EGW directly references the role of angels as ministering spirits to the heirs of salvation, which is the core concept of Hebrews 1:14.
"Hearing a voice, I turned to see who spoke to me. Then with dignity and solemnity One said, “Is this the celebration for the anniversary of the opening of the school? Is this the gratitude offering you present to God for the blessings He has given you? The world could render as acceptable an offering on this memorial occasion. The teachers are making the same mistake that has been made over and over again. They should learn wisdom from the experiences of the past. The careless, godless world can offer an abundance of such offerings as these, in a much more acceptable manner.” CT 350.3"
"To what purpose is the multitude of your sacrifices unto me? saith the Lord: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats."
Both passages address the idea that outward religious displays or offerings are meaningless if the heart is not right with God. EGW's passage echoes the sentiment of God rejecting insincere sacrifices found in Isaiah.
