He was delighted to find pagans whose philosophy, though not Christian in and of itself, was in some way compatible with Christianity. The third and final position we examined was that of Thomas Aquinas, who believed that all people could have a basic knowledge of God purely through natural reason. He did not agree with Augustine that the human mind had been totally corrupted by sin at the Fall. This belief led to his elevation of the power of the mind and his appreciation of philosophy. Theology is the higher form of wisdom, but it needs the tools of science and philosophy in order to practice its own trade.
Theology learns from philosophy, because ultimately theology is a human task.
How we view the relationship between faith and reason can have powerful implications for how the Christian engages society with the gospel. One of the problems with the apologetics of Tertullian is that he seemed to view all that opposed him to be enemies of the gospel, rather than as potential converts. This is in stark contrast to the behavior of the Apostle Paul in Acts 17, when he proclaimed the gospel among the Greeks at Mars Hill. He did not condemn them for their initial failure to accept the Resurrection. Instead, he attempted to reach common ground with them by quoting some of their own philosophers, picking out isolated statements from pagan thinkers which were consistent with Scripture, while still maintaining the absolute truth of Scripture as his foundation.
