Well we'll have to agree to disagree.

I will point out the fact that the enlightenment followed the translation of the Bible into common tongues and the distribution of it to the masses thanks to the invention of the printing press... By a Christian.

The concept of natural law being dependent upon Scripture and the Christian worldview finds its origins in the understanding that God, as the creator of the universe, has imbued it with inherent order and purpose. In the Christian worldview, this belief is rooted in the biblical account of creation, where God establishes order and design in the world.

According to Christian thought, natural law is seen as a reflection of God's eternal law, which governs the universe and is revealed through the created order. This perspective asserts that moral principles are not merely arbitrary commands from God but are rooted in the very nature of reality as designed by Him.

In the Christian tradition, the understanding of natural law has been influenced by thinkers such as St. Augustine and St. Thomas Aquinas. Augustine emphasized the idea that natural law is inscribed on the hearts of humanity, providing a universal moral compass that guides human conduct. Aquinas built upon this notion, arguing that natural law is derived from both human reason and divine revelation, with Scripture serving as a primary source of moral insight.

Therefore, in the Christian worldview, Scripture is considered essential for understanding and interpreting natural law because it provides divine revelation that illuminates the moral order inherent in creation. Through the lens of Scripture, Christians believe they can discern God's intentions for humanity and align their actions with His will, thus upholding the principles of natural law.

Everything ultimately points back to God. The law of God is written on every man's heart. Without that as a basis You are left with nothing but subjectivism.
