"At the time of the disappointment on October 22, 1844, Miller was worn and ill. He depended largely on his younger associates who stood with him in proclaiming the Advent message. They led him to reject the Sabbath truth as it came to his attention soon after the Disappointment. For this they, and not William Miller, will be held responsible. Ellen White writes of this experience on page 258 , and assures us that Miller will be among those who will be called from their graves at the sound of the last trump. EW 303.2"
"For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:"
Both passages refer to the resurrection of the dead at the sound of a trumpet. The EGW passage mentions Miller being resurrected at the last trump, while 1 Thessalonians 4:16 describes the Lord's descent with the trump of God and the resurrection of the dead in Christ.
Pages 232-240 , 254-258 : Three Angels’ Messages of Revelation 14 .—In a series of three chapters, beginning on page 232 , Ellen White discusses the first, second, and third angels’ messages. She was writing for those who with her had passed through the great Advent Awakening and the disappointments of the spring and fall of 1844. She did not attempt to enter into an explanation of these three messages, but assumed that her readers had a full knowledge of this experience. She presented that which would bring courage and understanding to her fellow believers in the light of their experience. We must turn to her book The Great Controversy for a detailed account of the burden of these messages. The first angel's message sounded the warning of the approach of the hour of God's judgment. See The Great Controversy , chapters “Heralds of the Morning,” pages 299-316 ; “An American Reformer,” pages 317-342 ; and “A Great Religious Awakening,” pages 355-374 . For the presentation of the message …
"And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,"
The EGW passage explicitly refers to the three angels' messages of Revelation 14, including the first angel's message. The KJV passage is the beginning of the first angel's message. This is a clear and direct reference.
