Theology and philosophy are arguably the two greatest fields of divine and human knowledge that precede and give birth to other disciplines, including natural and social sciences. However, the relationship between these two subjects has always been controversial. Scholars, who perceive theology and philosophy as two separate antagonistic disciplines, deny outright the role of the latter in the former. As a darkness, they contend that philosophy has no light to shed on the Christian faith. On the contrary, those who maintain that the two subjects are mutually related, argue that philosophy is not anti, but pro-faith. As a rational friendly ally, they claim that philosophy is a tool with which theologians explicate the articles of the Christian faith. In this paper, we analytically describe the two conflicting views on the relationship between theology and philosophy. Without denying the tension between them, we contend that philosophy, reason plays an indispensable role in the Christian faith and life precisely because professing the Christian faith without a rational explication of its doctrines reduces it to a fideistic and irrational religion.
