What happens

Augustine explains the significance of the number six as a perfect number, composed of its aliquot parts (1, 2, and 3), and argues that God completed creation in six days not out of necessity but to signify the perfection of His works through this number. He also defends the study of numbers as valuable for interpreting Holy Scripture.

Themes in this chapter

  • Divine Providence and History

    The six-day creation is presented as a deliberate act of divine order, with the number six symbolizing perfection and God's providential design.

Characters to notice

  • Augustine

    Author of the chapter, expounding on the perfection of the number six and its relation to God's creation.

  • Holy Scripture

    Referenced as the source of the six-day creation account and as containing numbers that require careful interpretation.

Key passages

  • These works are recorded to have been completed in six days (the same day being six times repeated), because six is a perfect number⁠—not because God required a protracted time, as if He could not at once create all things, which then should mark the course of time by the movements proper to them, but because the perfection of the works was signified by the number six.

    The six days of creation are not due to any limitation in God's power, but because the number six symbolizes perfection, representing the completeness of His work.

    Augustine clarifies that the six-day duration is symbolic, not a constraint on divine omnipotence.
