How can the moral law be discovered?

• A. Forming your conscience through reason, experience, and revelation
• B. Divine revelation alone
• C. Purely by personal feelings
• D. External authority only

Answer: (A)

Forming your conscience through reason, experience, and revelation is how the moral law becomes knowable and usable in real life. Reason helps you grasp basic goods—what things are truly good or bad in themselves—and to think through how they apply in different situations. Conscience is the inner judge that applies those truths to concrete choices, so it has to be formed, not left raw. Experience takes you through success and failure, teaching caution, humility, and the need for repeat reflection when new circumstances arise. Revelation provides the content of moral truth that reason alone might not fully uncover or correctly interpret, especially about God’s plan for human flourishing and the duties that flow from it. Together, they form a well-rounded guide that can discern what is truly good and how to live it.

Relying only on divine revelation misses the ongoing process of inner formation and critical reflection needed to apply moral truth to everyday life. Relying solely on personal feelings is unreliable because feelings change and can mislead; internal judgments require the clarity that reason and proper formation provide. External authority alone also falls short because it doesn’t cultivate the conscience or the ability to apply moral principles in new or complex situations.
