Systematic theology


Systematic theology, or systematics, is a discipline of Christian theology that formulates an orderly, rational, and coherent account of the doctrines of the Christian faith. It addresses issues such as what the Bible teaches about certain topics or what is true about God and God's universe. It also builds on biblical disciplines, church history, as well as biblical and historical theology. Systematic theology shares its systematic tasks with other disciplines such as constructive theology, dogmatics, ethics, apologetics, and philosophy of religion.

Method

With a methodological tradition that differs somewhat from biblical theology, systematic theology draws on the core sacred texts of Christianity, while simultaneously investigating the development of Christian doctrine over the course of history, particularly through philosophy, ethics, social sciences, and natural sciences. Using biblical texts, it attempts to compare and relate all of scripture which led to the creation of a systematized statement on what the whole Bible says about particular issues. In other words, "In reconstructing Christian teaching, systematic theology proceeds by a process of conceptual abstraction and schematization."
In a seminal article, "Principles of Systematic Theology," Anglican theologian John Webster describes systematic theology as proceeding along a series of principles, which he draws from various theologians including Thomas Aquinas:
  • The Trinity: The Ontological Principle
  • Scripture: The External/Objective Cognitive Principle
  • The Redeemed Intelligence of the Saints: The Internal/Subjective Cognitive Principle
Webster has also considered the task of all systematic theology as articulating the Creator/creature distinction, known also as the Categorical Distinction or the Infinite Qualitative Distinction, a concept also explored from the perspective of compatiblistic metaphysics by Kathryn Tanner in God and Creation in Christian Theology.
Within Christianity, different traditions the method employed to develop the system, b) the understanding of theology's task, c) the doctrines included in the system, and d) the order those doctrines appear. Even with such diversity, it is generally the case that works that one can describe as systematic theologies begin with revelation and conclude with eschatology.
Since it is focused on truth, systematic theology is also framed to interact with and address the contemporary world. Many authors have explored this area, including Charles Gore, John Walvoord, Lindsay Dewar, and Charles Moule. This process concludes with applications to contemporary issues.

Categories

Since it is a systemic approach, systematic theology organizes truth under different headings and there are certain basic areas, although the exact list may vary slightly. These are:
  • Angelology – The study of angels
  • Bibliology – The study of the Bible
  • Creationism – The study of creation
  • Hamartiology – The study of sin
  • Ecclesiology – The study of the church
  • Eschatology – The study of the end times
  • Soteriology – The study of salvation
  • Theological anthropology – The study of the nature of humanity
  • Theology proper – The study of the character of God, which is composed of Paterology, Christology and Pneumatology.

    History

The establishment and integration of varied Christian ideas and Christianity-related notions, including diverse topics and themes of the Bible, in a single, coherent and well-ordered presentation is a relatively late development. The first known church father who referred to the notion of devising a comprehensive understanding of the principles of Christianity was Clement of Alexandria in the 3rd century, who stated thus: "Faith is then, so to speak, a comprehensive knowledge of the essentials." Clement himself, along with his follower Origen, attempted to create some systematic theology in their numerous surviving writings. The first systematic theology in Latin was Lactantius's Divine Institutes, and the term Intitutio would set a precedence for works of systematic theology in the western tradition. In Eastern Orthodoxy, an early example is provided by John of Damascus's 8th-century Exposition of the Orthodox Faith, in which he attempts to set in order and demonstrate the coherence of the theology of the classic texts of the Eastern theological tradition.
In the West, Peter Lombard's 12th-century Sentences, wherein he thematically collected a great series of quotations of the Church Fathers, became the basis of a medieval scholastic tradition of thematic commentary and explanation. Thomas Aquinas's Summa Theologiae best exemplifies this scholastic tradition. The Lutheran scholastic tradition of a thematic, ordered exposition of Christian theology emerged in the 16th century with Philipp Melanchthon's Loci Communes, and was countered by a Calvinist scholasticism, which is exemplified by John Calvin's Institutes of the Christian Religion.
The 17th century saw a boom in focused systematic theologies within a renaissance of the scholastic method. Francis Turretin's Institutes of Elenctic Theology and Petrus van Mastricht's Theoretical-Practical Theology became touchstone works in the field, profoundly influencing later theologians like William Cunningham, Jonathan Edwards, Charles Hodge, and Herman Bavinck. Similarly, William Ames's systematic treatise, The Marrow of Theology '', would become the standard textbook for Harvard and Yale in their nascent years.
In the 19th century, primarily in Protestant groups, varieties of systematic theology arose that attempted to demonstrate that Christian doctrine formed a more coherent system premised on one or more fundamental axioms, often reasoned out as a form of dogmatic theology. Such theologies often involved a more drastic pruning and reinterpretation of traditional belief in order to cohere with the axiom or axioms, and continental theology divided between various schools of dogmatic theology, e.g. Erlangen Theology, Mediating Theology, classical confessionalism, and liberal theology. In the United States, Charles Hodge's Systematic Theology became a popular text in conjunction with his work at Princeton Theological Seminary. Significant for this period, Friedrich Daniel Ernst Schleiermacher's Der christliche Glaube nach den Grundsätzen der evangelischen Kirche espoused the fundamental idea of a universal presence among humanity, sometimes more hidden, sometimes more explicit, of a feeling or awareness of 'absolute dependence,' and this became a focal point of either acceptation, integration, or rejection among theologians. As such, systematic theology in the 19th century became a sophisticated endeavor of developing and articulating theology from certain assumed first principles, often on the back of the philosophical conversations inherited from Hegel, Kant, and Schleiermacher.
Systematic theology likewise saw a great variety of development into the 20th century, most notably with the advancement of Neo-Orthodoxy and the multivolume Church Dogmatics of Karl Barth. Helmuth Thielicke wrote his three-volume work, The Evangelical Faith, as a confessionally-Lutheran theology with existentialist emphases, and Wolfhart Pannenberg's three-volume Systematic Theology is an eclectic example of modernist systematics that attempts to integrate faith and science. Robert Jenson's two-volume Systematic Theology, stands as a final installment of 20th century systematic theology, looking to questions of postmodernity from a Barthian perspective. Several popular-level textbook-style works emerged during this period within Evangelical theology, from Lewis Sperry Chafer's eight-volume Systematic Theology to Wayne Grudem's stand-alone title Systematic Theology, a particularly sophisticated non-textbook example being the epistemological worldview theology of Carl F.H. Henry, contained in his six-volume God, Revelation and Authority. Reformed theology also saw considerable contributions in the twentieth century, including Louis Berkhof's popular Systematic Theology and G.C. Berkouwer's multivolume Studies in Dogmatics.'' The latter half of the twentieth century also saw the emergence of systematic theologies dealing with critical themes from social, political, and economic perspective, including the Liberation Theology of James Cone and Gustavo Gutiérrez, the Post-liberal Theology associated with Yale Divinity School, and Feminist Theology. As such, the variety and perspectives of systematic theology in the 20th century has tracked well with both the broadening of ethical concerns post-World War II, its expansive pluralism, and the advent of postmodernism.
