Natural theology is not universally, effectively, immediately, consistently, and infallibly communicated from above. Rather than originating from the mind of God, natural theology originates from the mind of man. Natural theology is man's attempt to discover the truth about God through empirical and rational analysis and philosophical speculation.Failure of Natural Theology, 16
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
