The Ultimate Proof for Christianity – Cornelius Van Til

TL;DR

Christianity’s ultimate proof lies in the presuppositional truth of the Bible.
Van Til’s apologetics asserts that all reasoning that excludes God is fundamentally flawed.
The Christian worldview is the only coherent basis for understanding reality.
Non-Christian worldviews are self-contradictory and cannot account for logic, morality, or science.
The triune God of Scripture is the necessary precondition for intelligibility and rational thought.

Presuppositional Truth of the Bible

Cornelius Van Til’s apologetic approach is grounded in the belief that the Bible’s truth is presuppositional, meaning it is the fundamental basis from which all understanding and reasoning must begin. According to Van Til, the ultimate proof for Christianity is not found through independent human reasoning but by starting with the presupposition that the Bible is the authoritative and inerrant Word of God. This aligns with Hebrews 11:6, which states, “And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.”

Van Til argued that to even engage in reasoning or to discuss evidence, one must first presuppose the existence of a God who is rational and has created a universe governed by order and logic. This presupposition is rooted in Scripture, as seen in Proverbs 1:7, “The fear of the LORD is the beginning of knowledge.”

The Christian Worldview as the Basis for Understanding

Van Til’s method emphasizes that the Christian worldview provides the only coherent basis for understanding reality. This worldview is based on the triune God revealed in Scripture, who is the ultimate standard of truth, morality, and beauty. In contrast, non-Christian worldviews fail to provide a consistent and logical foundation for knowledge, ethics, and rational thought.

This approach challenges the neutrality of human reason, arguing that all reasoning is inherently influenced by one’s presuppositions. As such, a worldview that excludes God leads to inconsistencies and contradictions. Van Til points to Romans 1:21, where Paul writes that although people knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking.

Self-Contradictory Nature of Non-Christian Worldviews

Van Til’s apologetics critically assesses non-Christian worldviews, demonstrating their self-contradictory nature. He contends that these worldviews cannot consistently account for the laws of logic, the uniformity of nature, or objective moral standards. For instance, a materialistic worldview cannot logically uphold abstract, universal laws like logic or morality, which are immaterial and unchanging.

This line of argumentation reflects the biblical assertion in 1 Corinthians 1:20, “Where is the wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world?” According to Van Til, only the Christian worldview, which acknowledges God’s sovereignty and revelation, can provide a coherent explanation for all aspects of existence.

The Necessity of the Triune God for Rational Thought

A key aspect of Van Til’s apologetics is the assertion that the triune God of Scripture is the necessary precondition for intelligibility and rational thought. This belief is grounded in the understanding that God’s nature and existence provide the foundation for all knowledge and truth.

Van Til’s argument is that without acknowledging the triune God, one cannot account for the diverse yet unified nature of reality. The doctrine of the Trinity, unique to Christianity, parallels the unity and diversity inherent in knowledge and existence. This concept is reflected in Colossians 2:3, which states that in Christ “are hidden all the treasures of wisdom and knowledge.”

Conclusion

Cornelius Van Til’s apologetic method presents the Christian faith as the only rational and consistent worldview, arguing that it provides the necessary presuppositions for knowledge, morality, and rational thought. This approach emphasizes the Bible’s authority and the necessity of the triune God for understanding reality.
