"Between the Trinity in its origins before time and the eschatological glorifying and unifying of God lies the whole history of God’s dealings with the world. By opening himself for this history and entering into it in his seeking love through the sending of Christ and the Spirit, God also experiences this history in its breadth and depth. We must drop the philosophical axioms about the nature of God. God is not unchangeable, if to be unchangeable means that he could not in the freedom of his love open himself to the changeable history of his creation. God is not incapable of suffering if this means that in the freedom of his love he would not be receptive to suffering over the contradictions of man and the self-destruction of his creation. God is not invulnerable if this means he could not open himself to the pain of the cross. God is not perfect if this means that he did not in the desire of his love want his creation to be necessary to his perfection."
