Conscience: Forming It and Following It

Conscience is God's voice within, and we must follow it, but we must also form it carefully through Scripture, prayer and Church teaching, because a conscience can be mistaken.

This is a summary of Lesson 5 of Grace, Virtue and Sin. The full lesson takes about 3 minutes in the Saints Light app.

What this lesson teaches

  • Conscience is the inner place where we hear God's law calling us to love good and avoid evil.
  • We must always follow a certain conscience, and no one may be forced to act against it.
  • Conscience can err, so we have a lifelong duty to form it by Scripture, prayer and Church teaching.
  • Ignorance we could not avoid lessens guilt; ignorance we chose does not.
