Children of the day

The knowledge of the angels being connected to evening and morning simply repeats itself in the days of creation. Morning indicates knowledge of their own spiritual “higher” order, albeit not what God is, while evening indicates a “lesser degree of knowledge”—that is, a knowledge of the lower order of creation. For Augustine, knowledge of a thing in the Word of God is “day,” while knowledge of its own specific nature is “evening.”—Early Christian Readings of Genesis One, page 283
