Catholic teaching on conscience

• Little else defines humanity than the gift of being able to personally distinguish good from evil and to choose between them.
• The inner voice that moves us to do good under any circumstances and to avoid evil by all means is called conscience.
• It is in the conscience that God speaks to us.
• Anyone who overlooks the conscience of a person, ignores it and uses coercion, violates that person’s dignity.
