KNOWLEDGE OBSCURED BY THE FALLEN ANGELS

Angels were expelled from heaven because they would not work in harmony with God. They fell from their high estate because they wanted to be exalted. They had come to exalt themselves, and they forgot that their beauty of person and of character came from the Lord Jesus. This fact the [fallen] angels would obscure, that Christ was the only begotten Son of God, and they came to consider that they were not to consult Christ. {TDG 128.2}
