Lucifer Was Next in Honor and Power to God’s Dear Son

Satan in heaven, before his rebellion, was a high and exalted angel, next in honor to God's dear Son. His countenance, like those of the other angels, was mild and expressive of happiness. His forehead was high and broad, showing a powerful intellect. His form was perfect; his bearing noble and majestic. A special light beamed in his countenance, and shone around him brighter and more beautiful than around the other angels; yet Jesus, God's dear Son, had the pre-eminence over all the angelic host. He was one with the Father before the angels were created. Satan was envious of Christ, and in his ambition (gradually) assumed command which devolved on Christ alone. — {ST January 9, 1879, par. 1}, (1SP 17.1) (SR 13.1)

Satan was once a covering cherub in the heavenly courts, the angel next in power to Christ Himself. — {CTr 200.2}

Among the inhabitants of heaven, Satan, next to Christ, was at one time most honored of God, and highest in power and glory. Before his fall, Lucifer, "son of the morning," was first of the covering cherubs, holy and undefiled. He stood in the presence of the great Creator, and the ceaseless beams of glory enshrouding the eternal God rested upon him. — ST, July 23, 1902 (18LtMs, Ms 140, 1903, par. 1}

[Satan was] the exalted angel who was given a position next to Jesus Christ in the heavenly courts. Lucifer was enshrouded with glory as the covering cherub. Yet this angel whom God had created, and entrusted with power, became desirous of being as God. He gained the sympathy of some of his associates by suggesting thoughts of criticism regarding the government of God. This evil seed was scattered in a most seducing manner; and after it sprung up and taken root in the minds of many, he gathered the ideas that he himself had first implanted in the minds of others and brought them before the highest order of angels as the thoughts of other minds against the government of God. Thus, by ingenious methods of his own devising, Lucifer introduced rebellion in heaven.  — {Lt162-1906.5; 1906}
