Christian Moral Life and Social Teaching

Christian Moral Life and Social Teaching

This domain tests how Catholics reason morally: the three sources of the moral act, conscience, sin, virtue, natural law, and the principles of Catholic social teaching from Rerum Novarum to Fratelli Tutti. The exam rewards structured moral analysis.

Core rules

  • The moral act has three sources: object, intention and circumstances. A good intention cannot justify an intrinsically evil object (CCC 1750-1756).
  • Conscience is a capacity for moral judgment that must be formed by Scripture, Church teaching, prayer and wise counsel. An erroneous conscience binds, but it does not make evil good (CCC 1790-1794).
  • Mortal sin requires grave matter, full knowledge and deliberate consent (CCC 1857). Venial sin weakens charity but does not sever communion with God.
  • Natural law is humanity's rational participation in God's wisdom (Rom 2:14-15; CCC 1954-1960). The theological virtues are faith, hope and charity; the cardinal virtues are prudence, justice, fortitude and temperance.
  • Catholic social teaching stresses human dignity, common good, subsidiarity, solidarity, option for the poor, universal destination of goods and care for creation.

Worked example

A legislator considers a housing bill that helps the poor but contains a provision permitting unjust eviction. Reasoning: the object is not only housing aid but also the eviction provision. If the unjust eviction is intended or is the means of achieving the good, the act is formally evil; if the provision is separable, the legislator may seek amendment or support the bill only if the evil is not intended and proportionate reason exists. Double effect cannot be used if the eviction is the chosen means. Verdict: the moral object must be assessed before consequences.

Traps

Consequentialism and proportionalism; claiming good ends justify evil means; reducing conscience to feeling; calling every sin mortal; treating subsidiarity as individualism; presenting Catholic social teaching as a party platform rather than a set of principles with prudential applications.
