Here’s John Piper’s summary of Jonathan Edwards’ view of the Trinity, that Piper says was revolutionary for him when he first started to read Edwards. It also blew my mind when I read this for the first time a few years back. This quote is taken from Jonathan Edwards On The Good Life, by Owen Strachan and Doug Sweeney.
“In brief, there is God the Father, the fountain of being, who from all eternity has had a perfectly clear and distinct image and idea of himself; and this image is the eternally begotten Son. Between this Son and Father there flows a stream of infinitely vigorous love and perfectly holy communion; and this is God the Spirit. God’s image of God and God’s Love of God are so full of God that they are fully divine Persons, and not less.”
