Scharlemann's more significant contributions to theology fall into two categories. First, Scharlemann has written a number of books and essays that investigate the nature of thinking theologically. These included the influential
The Being of God. The Death of God theologian
Thomas J. J. Altizer wrote in his autobiography that "Robert Scharlemann is the philosophical theologian who once most engaged me, and I regard his
The Being of God: Theology and the Experience of Truth as a truly seminal theological work. Here not only are philosophical and theological thinking truly united, but the Crucifixion is unraveled in thinking itself, and in pure thinking itself. ... Scharlemann's formula, 'the being of God when God is not being God,' is not simply an assault upon the metaphysical God, but upon every Godhead manifest apart from the Crucifixion..." In addition to this work, Scharlemann published a volume of essays entitled
Inscriptions and Reflections: Essays in Philosophical Theology. These further examine themes found in
The Being of God. Scharlemann is also known for his works interpreting the theological system of
Paul Tillich. Of decisive influence was his early work, Reflection and Doubt in the Thought of Paul Tillich (New Haven: Yale University Press, 1969). == Bibliography ==
