But rather than reject the claim that God is to be understood as the Holy Trinity, they have claimed that the doctrine is better explained without the claim that God is three persons but one substance, or with an interpretation of this claim that would have been unthinkable in past centuries. Robert Cummings Neville, the Dean of the Boston Theological Seminary, completely dismisses the claim, and defends the Trinity as three ways or aspects of divinity understood with reference to the creation.
God is the source of creation; He is the end or telos of creation, and He is the very activity of creation itself, according to Neville. Aside from this, there is little left of the traditional doctrine of the Trinity in Neville's theology.[^12] A more traditional defense of the Trinity is to be found in the work of a philosopher who teaches atNotre DameUniversity in Indiana, Thomas V Morris.
Morris uses the methods developed by analytic philosophers to defend a version of Social Trinitarianism from the heretical claim made by some process theologians that God is in need of the world.
Process theology itself developed as a reaction against a metaphysics of substances inspired by Whitehead and Hartshome's idea that the world consists of essentially interrelated events.[^13] Another contemporary metaphysical idea which has had an impact on discussions of the doctrine of the Trinity is the theory of relative identity. According to this idea the identity relation is always governed by the category of its terms.
Defenders of the Trinity such as Peter Geach and Peter van Inwagen have used the theory of relative identity to defend the proposition that while the persons of the Trinity may be different persons, they may at the same time be the same God.[^14] Other areas to which philosophers of religion have applied ideas drawn from contemporary logic and metaphysics include discussions of Anselm's ontological argument for the existence of God, the many problems pertaining to the divine attributes, the nature of divine activity, God's foreknowledge and human responsibility, the nature of creation ex nihilo and the problem of evil.
Older than epistemology and at least as ancient as metaphysics is ethics. Philosophical reflections on good and evil, right and wrong and virtue and vice have always mingled with religious thought, and today, as well, philosophers whose primary concern is the nature of value and morality are raising important questions for theologians to ponder.
