Kaufmann Kohler opens his systematic theology by defining theology itself, then immediately asks "What is Judaism?" and "The Essence of the Religion of Judaism." This triple framing—meaning, identity, essence—sets a pattern: each concept is first clarified, then historically traced, then distilled to its core. The table of contents reveals a deliberate architecture: Part I on God (chapters on attributes like holiness, wrath, love), Part II on Man (sin, repentance, immortality), Part III on Israel and the Kingdom of God (election, mission, messianic hope). Kohler, a leading Reform rabbi and president of Hebrew Union College, writes in 1918, engaging both traditional sources and modern science.

From Divine Attributes to Human Destiny

The structure moves from God's nature (omnipotence, omniscience, holiness) to God's relation to the world (creation, providence, evil, angels), then to humanity. In the excerpt on immortality, Kohler directly confronts modern science: "body and soul are seen to be indissolubly bound together by a reciprocal relation." He does not dismiss this but argues that the soul's God-likeness grounds belief in immortality. He rejects necromancy and sensory attempts to contact the dead, calling them "dangerous to the spiritual and moral welfare." Instead, he anchors immortality in the moral order: just as God rules with justice, so the soul beholds God beyond death.

Resurrection Reconsidered

Kohler treats resurrection as a historically conditioned belief. He describes the comforting image of the dead asleep in the earth, awakened by heavenly dew—a synagogal liturgical motif. But he then offers a choice: those who see God's power in miracles may retain the traditional "Reviver of the dead" formula; those who see God in immutable natural law will prefer the Union Prayer Book's phrase: "He who has implanted within us immortal life." This is not a dismissal but a respectful re-framing. Kohler cites Einhorn, a Reform pioneer, showing his lineage. The passage exemplifies his method: present the traditional view, acknowledge its emotional power, then offer a modern alternative consistent with scientific understanding.

Divine Retribution and Moral Order

In the chapter on divine retribution, Kohler begins with a universal principle: "The feeling of equity is deeply rooted in human nature." He then compresses Judaism's doctrine into Maimonides' formulation: God rewards good and punishes evil. The excerpt breaks off, but the pattern is clear: Kohler will trace this doctrine through biblical, rabbinic, and medieval sources, then address modern challenges. His approach is systematic—each chapter follows a similar arc: statement of the doctrine, historical development, and contemporary relevance. Readers should expect careful definitions and a willingness to adapt traditional concepts to modern thought without abandoning their moral core.

Reading Kohler's Method

Kohler's voice is measured, scholarly, and pastoral. He uses first-person plural ("we may interpret," "our spirit") to include the reader in the inquiry. He cites Psalm 73:26 and Maimonides, but also modern science and the Union Prayer Book. His footnotes (indicated by superscript numbers) reference a wide range of sources. The book is dense—161,000 words—but each chapter is self-contained. A first-time reader might start with a topic of personal interest (e.g., immortality, evil, or the mission of Israel) and then explore related chapters. The table of contents is a reliable guide: the three-part division makes the argument's progression clear.

Kohler's theology is both a historical survey and a constructive argument for a modern Judaism. He does not shy from difficult questions—how to reconcile traditional beliefs with science, how to reinterpret resurrection, how to maintain moral accountability. His answers are not dogmatic but reasoned, inviting the reader to weigh tradition against contemporary knowledge. This edition preserves his original 1918 text, including the preface, dedication, and index, offering a complete view of his systematic project.
