The Church believes there are objectively right and wrong answers to moral dilemmas. The process of moving from absolute values to general norms to specific case judgments requires the virtue of prudence, the ability to exercise sound judgment in practical matters, in order to arrive at moral certainty in one's judgments' (United States Conference of Catholic Bishops, 1991).

In the Catholic tradition, some rules apply in every situation. Reflection on these in light of the steps of moral decision making highlighted above should make it clear why these apply: 'One may never do evil so that good may result from it; The Golden Rule (from Jesus' Sermon on the Mount): 'Whatever you wish that others would do to you, do also to them' Charity always proceeds by way of respect for one's neighbour and his conscience: 'Thus sinning against your brethren and wounding their conscience…you sin against Christ.' Therefore 'it is right not to…do anything that makes your brother stumble'' (Catholic Bishops of Ontario, 2011 p. 325).
