as the transcendental argument for the existence of God. Clark held that the Scriptures constituted the axioms of Christian thought, which could not be questioned, though their consistency could be discussed. A consequence of this position is that God's existence can never be demonstrated, either by empirical means or by philosophical argument. In The Justification of Knowledge, the Calvinist theologian Robert L. Reymond argues that believers should not even attempt such proofs. Prophetic fulfillment In his book Science Speaks, Peter Stoner argues that only God knows the future and that Biblical prophecies of a compelling nature have been fulfilled. Apologist Josh McDowell documents the Old Testament prophecies fulfilled by Christ, relating to his ancestral line, birthplace, virgin birth, miracles, death, and resurrection. Apologist Blaise Pascal believed that the prophecies are the strongest evidence for Christianity. He notes that Jesus not only foretold, but was foretold, unlike in other religions, and that these prophecies came from a succession of people over a span of four thousand years. Origins apologetics Many Christians contend that science and the Bible do not contradict each other and that scientific fact supports Christian apologetics. The Catechism of the Catholic Church states that "The question about the origins of the world and of man has been the object of many scientific studies which have splendidly enriched our knowledge... These discoveries invite us to even greater admiration for the greatness of the Creator." The theologian and mathematician Marin Mersenne used celestial mechanics as evidence in his apologetic work, while Matteo Ricci engaged in scientific apologetics in China. In modern times, the theory of the Big Bang has been used in support of Christian apologetics. Several Christian apologists have sought to reconcile Christianity and science concerning the question of origins. Theistic Evolution claims that classical religious teachings about God are compatible with the modern scientific understanding about biological evolution and that the Creator God uses the process of evolution. Denis Lamoureux, in Evolutionary Creation: A Christian Approach to Evolution, states that "This view of origins fully embraces both the religious beliefs of biblical Christianity and the scientific theories of cosmological, geological, and biological evolution. It contends that the Creator established and maintains the laws of nature, including the mechanisms of a teleological evolution." The most radical example of a Christian-evolutionary synthesis is the work of Pierre Teilhard de Chardin, which was intended as apologetics to the world of science,
