Naturally Human, Supernaturally God seeks to open a small window upon an interesting case of theological convergence between three of the most important theologians of the pre-Conciliar period of Catholic theology, Rginald Garrigou-Lagrange O.P., Karl Rahner S.J., and Henri de Lubac S.J., each of whom played a vital role in the Second Vatican Council. The differences between these three figures sometimes seem to run so deep as to defy resolution. Yet Cooper argues they were strangely united in a shared conviction: todays church urgently needs to renew its acquaintance with an ancient Christian theme, the doctrine of deification.
