In its fullest and most robust sense, religion is the human person’s being in right relation to the divine, says Robert George, and all of us have a duty, in conscience, to seek the truth and to honor the freedom of all men and women everywhere to do the same:
. . . the existential raising of religious questions, the honest identification of answers, and the fulfilling of what one sincerely believes to be one’s duties in the light of those answers are all parts of the human good of religion. But if that is true, then respect for a person’s well-being, or more simply respect for the person, demands respect for his or her flourishing as a seeker of religious truth and as one who lives in line with his or her best judgments of what is true in spiritual matters. And that, in turn, requires respect for everyone’s liberty in the religious quest—the quest to understand religious truth and order one’s life in line with it.
Because faith of any type, including religious faith, cannot be authentic—it cannot be faith—unless it is free, respect for the person—that is to say, respect for his or her dignity as a free and rational creature—requires respect for his or her religious liberty. That is why it makes sense, from the point of view of reason, and not merely from the point of view of the revealed teaching of a particular faith—though many faiths proclaim the right to religious freedom on theological and not merely philosophical grounds—to understand religious freedom as a fundamental human right.
