Augustine of Hippo on "Better" and "Greater"

I found this quote in Augustine's writings that I'm still mulling over. Augustine says: "In things in which greatness goes not by bulk, being greater means being better" (De Trinitate Vi, 9).

Could this passage constitute a response to those Trinitarians who contend that "greater" does not mean "better" in John 14:28?
