Bonaventure’s Breviloquium, part 5
According to Bonaventure, why did God bring physical nature into existence over the course of six days? Because of the Trinity, of course. Here’s how he correlates the two:
Because all things flow from the first and most perfect Principle, who is omnipotent, all wise, and all-beneficent, it was most fitting that they should come into being in such a way that their very production might might reflect these same three attributes or perfections. Therefore, the divine operations that fashioned the world machine was three-fold: creation, particularly reflecting omnipotence; distinction, reflecting wisdom; and embellishment reflecting unbounded goodness. (Breviloquium 2.2.2)
God’s power, he goes on to explain, was exhibited in God’s bringing the world into being from nothing “before any day,” his wisdom in his work of distinction over the first three days, and his goodness in his work of embellishment or adornment in the second three days. As he had argued earlier, these three attributes of omnipotence, wisdom, and goodness are “appropriated” by the persons of the Father, the Son, and the Holy Ghost. So, in creating the world in six days, God displayed the Trinity.
