if divine revelation is rejected, philosophers cease to have access to the knowledge needed to keep God's transcendence and immanence in balance. And without God being both transcendent and immanent, as effectively communicated in natural and special revelation, some form of deism or pan(en)theism emerges.Failure of Natural Theology, 23
Natural theology seeks to obtain a philosophical knowledge of God by suppressing the knowledge of God that comes through natural revelation.Failure of Natural Theology, 22
Natural theology, unlike revealed theology, does not start with God's self-disclosure. Natural theology, at least for Aquinas, begins on the false notion that man is ignorant of God. Rather than starting out with the immediate knowledge and awareness of God, natural theology seeks to construct a knowledge of God through reason and experience.Failure of Natural Theology, 11
general revelation refers to what God makes known of himself through creation. It is accepted and understood by faith. It proceeds from God and reaches us. On the other hand, natural theology, as it is called, refers to attempts by humans to argue for the existence and nature of God based on what is known or observed in creation and providence. It assumes that we have the capacity to know a great deal about God on the basis of our own powers of reason and observation.Systematic Theology, 55-56
