442 Part Three The more a correct conscience prevails, the more do per- sons and groups turn aside from blind choice and try to be guided by objective standards of moral conduct. 61 IN BRIEF 1795 “Conscience is man’s most secret core, and his sanctu­ ary. There he is alone with God whose voice echoes in his depths” ( GS 16). 1796 Conscience is a judgment of reason by which the human person recognizes the moral quality of a con- crete act. 1797 For the man who has committed evil, the verdict of his conscience remains a pledge of conversion and of hope. 1798 A well-formed conscience is upright and truthful. It formulates its judgments according to reason, in con- formity with the true good willed by the wisdom of the Creator. Everyone must avail himself of the means to form his conscience. 1799 Faced with a moral choice, conscience can make either a right judgment in accordance with reason and the divine law or, on the contrary, an erroneous judgment that departs from them. 1800 A human being must always obey the certain judg- ment of his conscience. 1801 Conscience can remain in ignorance or make errone- ous judgments. Such ignorance and errors are not always free of guilt. 1802 The Word of God is a light for our path. We must assimilate it in faith and prayer and put it into practice. This is how moral conscience is formed. 61 GS 16. 1751
