This book breaks new ground in bringing together the work of some significant systematic and philosophical theologians on the doctrine of the Trinity. Theologians and analytic philosophers of religion have both done substantive work on the Trinity -- but have done so in isolation from one another. In Which Trinity? Whose Monotheism? Thomas H. McCall creatively engages such philosophers of religion as Richard Swinburne and Brian Leftow and such influential theologians as Jürgen Moltmann, Robert Jenson, and John Zizioulas. Among all the currently available books on the doctrine of the Trinity, no other book brings analytic philosophers of religion into such direct conversation with mainstream theologians on this score.
