It's kind of a corny story, but I remember one day when I was taking a walk in the Arnold Arboretum and all of a sudden some of St. Bonaventure became clear to me. For his feast day today, I was just thinking through that moment again, and thanking God for the Seraphic Doctor.
I was looking at a tree and I became aware that the tree had the power, through the use of my senses, to introduce an idea of itself into my mind. That the tree should have this power is a vestige of the generation of the Son from the Father.
God the Father, Who is the Fontal Fullness of being, eternally emanates a perfect Idea of Himself; this is the generation of the Son from the Father, the Eternal Word from the Source. According to different degrees of similarity, this primal dynamic of emanation comes to be embedded in everything else that has being. As rational creatures created in the image and likeness of God, we become aware of this in the capacity of existing things to 'process' an idea of themselves into our minds.
Among many other things, that's an insight for which I'm thanking St. Bonaventure today; that we can know and love other creatures precisely because we were created as a footprint of this Primal and Delighted Overflowing called the Blessed Trinity.
