Here’s a snippet from Dr. West,

Millard Erickson’s little book on the trinity appeared in 2009 and addressed a then widely debated aspect of Trinitarian theology: Subordinationism.  The old proverb says ‘there’s nothing new under the Sun’, however and when it comes to every possible feature of trinitarian theology it has all been said before.  Erickson here simply re-addresses an issue long ago addressed and then addressed again and then again in what seems to be every two or three generations since the early Fathers complained about Arius and his heretical notions.
