Sacramental Universe

Randall C. Zachman writes:

This metaphor [of the heavens preaching from Ps 19] recalls Calvin’s fondness for Augustine’s dictum that the sacraments are “visible words” of God, and indicates his willingness to extend this sacramental way of speaking to the self-disclosure of God in the universe. Calvin reinforces the theme of visible words in his interpretation of the fourth verse, in which he uses the metaphor of the orations of a teacher. He then combines this similitude of teaching and preaching with the metaphor of a written volume set forth for us to read.

This view of the "book" of the universe as sacramental might be strengthened if one were willing to think of God's other book, the Scriptures, as specially sacramental.
