Systematic Theology: Chapter One

Theology as Faith Seeking Understanding
The word “theology” is derived from the combination of two Greek words: θεός (theos) + λόγος (logos), meaning the “study of God.” In its broadest sense, systematic theology is that branch of Christian theology that has to do with systematic and organized reflection on the subject matter of Christian faith. Augustine of Hippo is known for the saying “Crede ut intelligas” (“Believe that you may understand”).1 Anselm of Canterbury modified this as “Credo ut intelligam” (“I believe in order to understand”), and Anselm’s motto fides quaerens intellectum (“faith seeking understanding”) is a helpful definition of theology.2 Thomas Aquinas identified Sacra Doctrina (Holy Teaching or Sacred Doctrine) as the “science of God” and of all other things insofar as they have reference to God. Sacra Doctrina is the “highest wisdom” because it deals with the Highest Cause insofar as God (meaning the triune God) has made himself known in revelation.3 John Calvin wrote in his Institutes of the Christian Religion that theology had to do with the knowledge of God and of ourselves that leads to immortality.4
More recently, Thomas Oden writes that the subject matter of theology is the “Living God,” YHWH, “known in the faith of the worshiping Christian community” which lives out of Jesus Christ’s resurrection, and of all things as they relate to God. God is a personal Subject, a You or Thou, not an it. Theology is the “investigation and clarification of the internal consistency of [the church’s confessional] assertions . . . and the way they relate to the problems of daily life.”5
Karl Barth adds that the task of theology is in the service of the church. Theology exists in “the realm between the Scriptures and their exposition and proclamation.” Theology “is based upon the fact that God has spoken to humanity and that humanity may hear God’s word through grace.” Theology reminds the church that its life and work are “under the authority of the gospel and the law, that God should be heard.”6
The language of the previous paragraphs helps to unravel the meaning of theology. First, faith: In Greek, the single word πιστεύω (pisteuō)) can be translated either “I believe” or “I have faith,” and the corresponding noun πίστις (pistis) can be translated as either “belief” or “faith.” This ambiguity explains the contradiction that is not really a contradiction between the apostle Paul in his letters to the Romans and the Galatians and the epistle of James concerning justification by faith. Paul states in Romans 3:28 “that a human being is justified by faith apart from the works of the law (δικαιοῦσθαι πίστει ἄνθρωπον χωρὶς ἔργων νόμου, dikaiousthai pistei anthrōpon chōris ergōn nomou),” while James writes that “a human being is justified by works and not by faith alone” (ἐξ ἔργων δικαιοῦται ἄνθρωπος καὶ οὐκ ἐκ πίστεως μόνον, ex ergōn dikaioutai anthrōpos kai ouk ek pisteōs monon, James 2:24).
That the contradiction is only verbal becomes clear in James 2:19 when James writes: “You believe (πιστεύεις, pisteueis) that God is one; you do well. Even the demons believe (πιστεύουσιν, pisteuousin)—and shudder.” As the English translation makes clear, James is understanding “faith” in the sense of an intellectual conviction: the demons believe that God exists. To the contrary, the apostle Paul uses the word “faith” in the sense of “trust,” not mere intellectual conviction. The demons may believe that there is a God, but they have not placed their complete trust and reliance on him in the manner in which Paul talks about justification by faith. In English, we mark the same distinction as one between “belief that” and “belief in.”
Latin distinguishes between fides qua and fides quae. Fides qua means “the faith which believes.” It refers to the subjective activity of “believing in” or “having faith.” This is the faith that justifies by trusting in Jesus Christ alone for salvation. Fides quae means “the faith which is believed.” This is the objective reality in which we place our faith. When the presiding minister says at the celebration of the Eucharist, “Let us confess our faith in the words of the Nicene Creed,” he or she is referring to faith in the sense of fides quae. The Apostles’ and Nicene Creeds are summaries of this subject matter of the Christian faith: “God the Father Almighty, Maker of heaven and earth,” “one Lord Jesus Christ, the only Son of God,” “the Holy Spirit, the Lord and giver of Life.” Father, Son, and Holy Spirit – these are the three triune persons who simply are the one God. This triune God is the objective reality in whom Christians place their faith, and the Creeds provide a short outline of who this God is, and what this God has done. Theology thus includes both fides qua and fides quae. “Faith seeking understanding” is the process by which those who have faith in the subjective sense (fides qua) come to understand and reflect about the object (or subject matter) of that faith (fides quae), that triune reality in which faith puts its trust.
What Faith Is Not
A description of theology as “faith seeking understanding,” helps to clear up some all too prevalent misunderstandings of the nature of both theology and faith. First, faith is not “fideism,” the common misconception that “faith” means implausible belief divorced from reason, that faith is mere credulity, or, in the words of the White Queen in Alice Through the Looking Glass, believing in “impossible things.”7
