In the official formulation of Tillich's theology, the ontological polarity of dynamics and form, together with the other polarities, provides the basic symbolic material for the description of the divine life. In that life dynamics and form are balanced, with the tensions and disruptions characteristic of finite life wholly overcome. “Being comprises becoming and rest, becoming as an implication of dynamics and rest as an implication of form. If we say that God is being-itself, this includes both rest and becoming, both the static and the dynamic elements” (ST I 247). At the same time, however, we find that Tillich identifies God or being-itself with the power of being (ST I 110, 180, 2O5f., 230, 236f., 272; ST II 10f.). Although he does not and perhaps would not identify dynamics with the power of being, we find that they have extremely similar characteristics. In fact we are driven to ask why the element of dynamics within the divine life is not identified with the power of being, and to speculate on the consequences of such an identification. It is our contention that the internal logic of Tillich's analysis of this polarity is such that he cannot finally avoid identifying divine dynamics with the creative power of being. This, in turn, entails that God is a being rather than beyond being, himself an instance of the power of being pervasively inherent in all beings. In the first section we shall consider the polarity of dynamics and form as it functions in finite beings. Then we shall examine its role in the divine life and its relationship to the power of being.
