Bonaventure — on Wis 8:2 (Collations on the Hexaemeron, Collation 11)

“From the second foursome, let us take wise, for it contains the other three. If He is wise, He is therefore living; and if living, He is powerful; and if powerful, beautiful also, for wisdom is the most beautiful form: wherefore "I was enamored of her beauty." Out of the third foursome, let us take one attribute: happy, which contains within itself the other three. For if He is a happy Spirit, therefore He is good, and hence just, and also holy. And so, in these three attributes, eternal, wise, and happy, the whole Trinity shines forth, for eternity is appropriated to the Father, wisdom to the Son, and happiness to the Holy Spirit.”
