Catechism of the Catholic Church

"Nobody may be forced to act against his convictions, nor is anyone to be restrained from acting in accordance with his conscience in religious matters in private or in public, alone or in association with others, within due limits." This right is based on the very nature of the human person, whose dignity enables him freely to assent to the divine truth which transcends the temporal order. For this reason it "continues to exist even in those who do not live up to their obligation of seeking the truth and adhering to it." (160, 1782, 1738)
