"To dispute the supremacy of the Son of God, thus impeaching the wisdom and love of the Creator, had become the purpose of this prince of angels. To this object he was about to bend the energies of that master mind, which, next to Christ's, was first among the hosts of God. But He who would have the will of all His creatures free, left none unguarded to the bewildering sophistry by which rebellion would seek to justify itself. Before the great contest should open, all were to have a clear presentation of His will, whose wisdom and goodness were the spring of all their joy. PP 36.1"
"That all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him."
Both passages emphasize the importance of honoring the Son (Jesus/Christ). While EGW doesn't directly quote John 5:23, the underlying principle of honoring the Son as one honors the Father is present in both texts, making it a thematic parallel.
"For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:"
Both passages deal with the creation of all things by Christ and the implications of that creation for the heavenly host. EGW expands on the idea that Christ's role was challenged, which is implied in Colossians 1:16.
The King of the universe summoned the heavenly hosts before Him, that in their presence He might set forth the true position of His Son and show the relation He sustained to all created beings. The Son of God shared the Father's throne, and the glory of the eternal, self-existent One encircled both. About the throne gathered the holy angels, a vast, unnumbered throng—“ten thousand times ten thousand, and thousands of thousands” ( Revelation 5:11 .), the most exalted angels, as ministers and subjects, rejoicing in the light that fell upon them from the presence of the Deity. Before the assembled inhabitants of heaven the King declared that none but Christ, the Only Begotten of God, could fully enter into His purposes, and to Him it was committed to execute the mighty counsels of His will. The Son of God had wrought the Father's will in the creation of all the hosts of heaven; and to Him, as well as to God, their homage and allegiance were due. Christ was still to exercise divine power, …
"And I beheld, and I heard the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands;"
EGW directly quotes Revelation 5:11 to describe the vast number of angels present before the throne of God.
"And again, when he bringeth in the firstbegotten into the world, he saith, And let all the angels of God worship him."
Both passages discuss the worship of Christ by the angels. Hebrews 1:6 explicitly states that the angels should worship Him, while EGW describes a scene where the angels are gathered to acknowledge Christ's position and due homage.
The angels joyfully acknowledged the supremacy of Christ, and prostrating themselves before Him, poured out their love and adoration. Lucifer bowed with them, but in his heart there was a strange, fierce conflict. Truth, justice, and loyalty were struggling against envy and jealousy. The influence of the holy angels seemed for a time to carry him with them. As songs of praise ascended in melodious strains, swelled by thousands of glad voices, the spirit of evil seemed vanquished; unutterable love thrilled his entire being; his soul went out, in harmony with the sinless worshippers, in love to the Father and the Son. But again he was filled with pride in his own glory. His desire for supremacy returned, and envy of Christ was once more indulged. The high honors conferred upon Lucifer were not appreciated as God's special gift, and therefore, called forth no gratitude to his Creator. He gloried in his brightness and exaltation and aspired to be equal with God. He was beloved and reverenc…
"And I beheld, and I heard the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands; Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing."
Both passages describe angels worshipping and praising. While Revelation 5:11-12 focuses on the Lamb, and EGW focuses on Christ, the general theme of angelic worship is present in both. The connection is not as strong as a direct allusion, but it's a valid thematic parallel.
