For those who believe that we should excise all philosophy from theology do not realize that all of us use philosophical concepts and terms whether we realize it or not. He who believes he is free from philosophy is the likely unwitting adherent to the philosophical teaching of a defunct philosopher or theologian. Rather than run from natural knowledge, or philosophy, we should seek God’s wisdom wherever we find it. Subject to the magisterial authority of Scripture, true philosophy never conflicts with sacred theology.
The Christian and Philosophy

What does Jerusalem have to do with Athens? This was the famous statement made by Tertullian when he challenged the supposed connections between theology and philosophy, the naturally obtained wisdom of humans. From one vantage point, Tertullian echoes the teaching of Scripture. Recall the words of the Apostle Paul: “The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned” (1 Cor. 2:14). Philosophical knowledge can never serve as a ladder to heaven. For all of their learning, philosophers have never been able to glean the message of the gospel through the power of their own thought or from reflecting on the creation. The saving knowledge of Christ and his gospel is solely the provenance of special revelation and the sovereign regenerative work of the Holy Spirit. To the natural person, the gospel is a stumbling block and folly (1 Cor. 1:23).
The Queen and the Handmaid
But does the antithesis between earthly philosophy and the heavenly knowledge of salvation completely define the relationship between the two disciplines? Is there no function whatsoever for philosophy in theology? While some may latch on to Tertullian’s statement and try to excise all philosophy from theology, historically, the church has admitted a carefully defined role for philosophy in relation to theology. Protestant theologians have acknowledged that theology is the queen of the sciences. That is, theology has a regulative function among the various disciplines of knowledge because of its supernatural source. This is not to say that theology speaks exhaustively to every single conceivable discipline but that it nevertheless serves as a referee to ensure that other disciplines do not cross divinely given moral and ethical boundaries. The Westminster Confession (1647) captures the magisterial role of theology when it states: “The supreme judge by which all controversies of religion are to be determined . . . can be no other but the Holy Spirit speaking in Scripture” (I.x). Good theology has its roots in the rich soil of Scripture and thus serves as the queen of the sciences. But theology’s magisterial role does not therefore preclude the responsible use of philosophy. Protestant theologians recognize that theology is queen of the disciplines and that philosophy is a handmaiden, an ancillary tool that the church may use in the task of doing theology. Or in other words, there is a role for a scripturally subordinated use of natural revelation in concert with special revelation. In the words of the Belgic Confession (art. II), we can use God’s two books, the books of Scripture and nature as we formulate our biblical doctrines.
How have theologians used philosophy in theology? Two examples illustrate the role of philosophy in theology. Despite the fact that Tertullian wanted to distance Jerusalem from Athens, he nevertheless employed philosophical categories such as substance to distinguish the three persons of the godhead from their commonly shared essence.
