Each person should have a right conscience and follow it. A Catholic should form a right conscience by learning the Faith and obeying the teaching authority, or Magisterium, of the Catholic Church.

Moreover, the moral life of Christians is guided by the grace and Gifts of the Holy Spirit. We do not always know with certainty whether our consciences are right, but we can train them over a period of time to be evermore aware of the Truth, by listening to the Word of God in Scripture and in the Church’s teaching, and by being attentive to the inspiration of the Holy Spirit within us.
