Conscience

Conscience is the interior voice of a human being, within whose heart the inner law of God is inscribed. Moral conscience is a judgment of practical reason about the moral quality of a human action — it moves a person at the appropriate moment to do good and to avoid evil (CCC 1777–1778).

What Conscience Is

Conscience is not merely a feeling or social instinct. It is the practical judgment of reason applied to a specific situation — the voice within that says "do this" or "do not do this" and which passes judgment on what has been done. The Catechism calls it "man's most secret core and sanctuary" (CCC 1776–1777).

The Dignity of Conscience

The Church teaches that every human being has a right and duty to follow their conscience — and no one may be forced to act against it (CCC 1782). But this dignity assumes conscience is properly formed — genuinely seeking what is truly right, not merely rationalizing what is preferred.

The Formation of Conscience

An erroneous conscience — one that judges wrongly because it has been poorly formed — does not eliminate moral responsibility. This is why the Church insists on the formation of conscience: through prayer, study of Scripture and the Catechism, regular reception of the sacraments, and attention to the Church's moral teaching (CCC 1783–1785).

Frequently Asked Questions

Can a Catholic follow their conscience against Church teaching? The Magisterium forms and guides conscience, not replaces it. A conscience that consistently contradicts the definitive teaching of the Church on faith and morals needs to be reformed, not followed. Conscience and the Magisterium are not in opposition — one serves the other (CCC 2039).

What is an examination of conscience? The prayerful practice of reviewing one's thoughts, words, and actions in light of God's law — recommended before every Confession and ideally made daily (CCC 1454).
