The Church has been called to form consciences not to replace them' (Pope Francis, 2016 Amoris Laetitia 37). The Catholic tradition teaches that a person is obliged to follow his or her conscience. This teaching takes into account the way in which the individual's desire for what is good, and his or her capacity to reason about what is good and right, and choose freely to do what is morally right, are related to the idea of objective moral truth. Though we frequently talk about conscience as if it were a thing, it is really an abstract construct that is used to talk about how we engage morally with the world. Conscience, literally translated from its Latin root, means with knowledge. At its simplest level then, to act in good conscience, or to follow one's conscience, is to act in way that is in accordance with the knowledge that one has about a particular situation.
