How Theology Differs from the Other Sciences

"Although theology treats of the same things with metaphysics, physics and ethics, yet the mode of considering is far different. It treats of God not like metaphysics as a being or as he can be known from the light of nature, but as that Creator and Redeemer made known by revelation. It treats of creatures not as things of nature, but of God (i.e., as holding a relation and order to God as their Creator, preserver and Redeemer) and that too according to the revelation made by him. This mode of considering, the other sciences do not know or do not assume" (Francis Turretin, Institutes of Elenctic Theology, 1:17).
