His rationalism made him god over God. In every sphere of life and thought, autonomy invites anarchy. Van Til rightly observed that the choice is between autonomy and theonomy, self-law and God's law. In the twentieth century, churches have succumbed to autonomous spirituality, divorced from God's law on the one hand, and autonomous rationalism. Instead of autonomous man, the sovereign God must be the starting point of all thinking.
Autonomous reason ends in irrationalism and blasphemy.
