Saadia, in his "Book of Beliefs and Opinions" (אמונות ודעות) grapples with the following conundrum: throughout the Tanakh, Prophets frequently describe their visions of the divine realm. These descriptions include majestic images of God sitting on His heavenly throne, surrounded by the heavenly host. Since believing that God has perceivable, physical features is blasphemous for Saadia, he concludes that the visions do not portray God, but rather portray God's created glory. This glory is God's created messenger, his exalted angel, created to give the prophets something concrete to visualize.
