The most valuable aspect of A Trinitarian Anthropology may be that it presents us with a method of engaging theological difference that makes cuts and divisions when necessary, but never departs from a truly Catholic understanding of orthodoxy and always keeps an eye towards ecclesial harmony." - Theological Studies "Schumacher's work is a detailed, competent study of one of the important issues in contemporary Catholic theology: a careful comparison of the theological anthropology of Hans Urs von Balthasar and Adrienne von Speyr with that of Thomas Aquinas. Such a serene, objective treatment, combined with Schumacher's respect and empathy for all three theologians, is indeed rare... Schumacher's magnum opus is undeniably a milestone in the ever-expanding and deepening research evaluating the immense theological and spiritual heritage of Hans Urs von Balthasar and Adrienne von Speyr within the Catholic theological tradition." -The Thomist
