our lives, personally and communally, on God's reality." The 1999 Pittsburgh Statement of Principles declared the "reality and oneness of God". British Liberal Judaism affirms the "Jewish conception of God: One and indivisible, transcendent and immanent, Creator and Sustainer". Revelation The basic tenet of Reform theology is a belief in a continuous, or progressive, revelation, occurring continuously and not limited to the theophany at Sinai, the defining event in traditional interpretation. According to this view, all holy scripture of Judaism, including the Torah, were authored by human beings who, although under divine inspiration, inserted their understanding and reflected the spirit of their consecutive ages. All the People of Israel are a further link in the chain of revelation, capable of reaching new insights: religion can be renewed without necessarily being dependent on past conventions. The chief promulgator of this concept was Abraham Geiger, generally considered the founder of the movement. After critical research led him to regard scripture as a human creation, bearing the marks of historical circumstances, he abandoned the belief in the unbroken perpetuity of tradition derived from Sinai and gradually replaced it with the idea of progressive revelation. As in other liberal denominations, this notion offered a conceptual framework for reconciling the acceptance of critical research with the maintenance of a belief in some form of divine communication, thus preventing a rupture among those who could no longer accept a literal understanding of revelation. No less importantly, it provided the clergy with a rationale for adapting, changing and excising traditional mores and bypassing the accepted conventions of Jewish Law, rooted in the orthodox concept of the explicit transmission of both scripture and its oral interpretation. While also subject to change and new understanding, the basic premise of progressive revelation endures in Reform thought. In its early days, this notion was greatly influenced by the philosophy of German idealism, from which its founders drew much inspiration: belief in humanity marching toward a full understanding of itself and the divine, manifested in moral progress towards perfection. This highly rationalistic view virtually identified human reason and intellect with divine action, leaving little room for direct influence by God. Geiger conceived revelation as occurring via the inherent "genius" of the People Israel, and his close ally Solomon Formstecher described it as the awakening of oneself into full consciousness of one's religious understanding. The American theologian Kaufmann Kohler also spoke of the
