Many of say that conscience rights is under attack. And with good reason. Take for instance the US Senate’s recent rejection of conscience rights viz. President Obama’s healthcare fiasco. So, a reasonable question is what the understanding of the role of conscience in moral decision making?

The Catechism of the Catholic Church (par. 1790-93) states the following about erroneous judgement:

A human being must always obey the certain judgment of his conscience. If he were deliberately to act against it, he would condemn himself. Yet it can happen that moral conscience remains in ignorance and makes erroneous judgments about acts to be performed or already committed.
