Dignitatis humanae

"All men are bound to seek the truth, especially in what concerns God and his Church, and to embrace it and hold on to it as they come to know it."

"This Vatican Council declares that the human person has a right to religious freedom. This freedom means that all men are to be immune from coercion on the part of individuals or of social groups and of any human power, in such wise that no one is to be forced to act in a manner contrary to his own beliefs, whether privately or publicly, whether alone or in association with others, within due limits."

"It is one of the major tenets of Catholic doctrine that man’s response to God in faith must be free: no one therefore is to be forced to embrace the Christian faith against his own will."
