The new council stressed Jesus consubstantiality, coeternity and coequality with the Father. Yet their models had the opposite effect, stressing the individuality of the persons. Augustine , who comes somewhat later, is representative of the approach of the West, which by its analogies stressed God's oneness . Since we are in the image of God, Augustine reasoned that our nature might reflect God's triunity. He begins with 1 Jn 4 's statement that God is love.
Further analogies build on the notion of love, and draw on the inner world of thought.
Since we are in God's image, our minds bear traces of the Trinity in its triadic structures. In Him, the three are one. And again, no one person of the Trinity can be identified with any one element of the triad. The second analogy is memory, understanding, and will. Memory contains all that we know, even when we are not thinking of it.
