Luke 12:56-57 has Jesus rebuke the crowds: 'You hypocrites!... why do you not judge for yourselves what is right?'
Refutation
In context, Jesus is addressing crowds who competently read ordinary weather signs (interpreting sky and wind to predict rain or heat) yet fail to discern the eschatological signs of the present moment — his own arrival and the coming judgment. 'Judge for yourselves what is right' (v. 57) leads directly into a practical wisdom illustration (vv. 58-59) about urgently settling matters with an accuser before judgment — it is a call to apply the ordinary, God-given moral perception people already possess, which they are currently failing to exercise, not a rejection of revealed law in favor of pure autonomous reason. This coheres with the robust natural law strand running through both Testaments: Paul argues that even Gentiles 'who do not have the law... show that the work of the law is written on their hearts' (Rom 2:14-15), and that God's nature is perceptible through creation itself (Rom 1:19-20). The objection assumes a false dichotomy between general revelation (a real, if imperfect, natural moral capacity available to all people) and special revelation (Torah, the words of Christ) — classical Christian ethics, especially the Thomistic natural law tradition, has always held these as complementary, not competing: special revelation clarifies, corrects, and completes what natural reason grasps only partially and often actively suppresses (Rom 1:18).
Positive case
The natural law tradition (Aquinas, Summa Theologiae I-II.94, building on Rom 2:14-15) holds that all people possess real, if imperfect, access to basic moral truth through reason and conscience, while special revelation supplies what fallen reason alone tends to suppress or distort — this positive account explains why Jesus can appeal to people's own moral judgment without thereby discarding revealed ethical teaching.
Steelmanned objection
Here Jesus tells people to figure out morality for themselves through their own reasoning rather than simply obeying revealed commands — which sits in tension with a Bible that elsewhere grounds ethics in direct divine command and obedience, suggesting either an internal inconsistency in biblical ethics, or a concession that natural human moral reasoning is sufficient on its own, undercutting the need for revealed law and scripture in the first place.
Incoherence of the alternative
If unaided human reason alone were fully sufficient for reliable moral knowledge, as a strict rationalist reading of this verse would require, it becomes very hard to explain why societies relying purely on reason have historically diverged so catastrophically on major moral questions — practicing slavery, infanticide, and mass violence at scale while calling it reasonable. The doctrine of sin's noetic effects (reason's grasp of moral truth being real but impaired and prone to self-serving suppression, as Rom 1 predicts) explains this pattern; a purely secular rationalism, which expects reason to be a reliable, unbiased moral guide, has no comparable explanatory resource for why it so often is not.
