Social philosophers and theologians prioritize the demands of justice whenever they conflict with agape’s claims. They do so based on the following implicit rules, namely: (1) Perfect duties take precedence over imperfect duties. (2) Subsistence test—whatever is critical for society’s existence has primacy. (3) Legal debt takes priority over moral debt. Both economic history and praxis validate the need to prioritize the claims of justice. After all, it provides critical legal institutional preconditions for the creation and protection of markets. It provides the economic guardrails to prevent anti-social preferences and transactions. It is essential to getting around collective-action problems.
