In an interview with Christianity Today, social critic Os Guinness explains why religious liberty it necessary for societal flourishing:
Americans employ the term “religious freedom,” while Europeans prefer the roughly synonymous term “freedom of religion and belief.” In the book, you suggest something deeper and broader with the term “soul freedom.” What is “soul freedom”?
“Soul Liberty” was Roger Williams’s magnificent term for religious freedom. It stands over against those who confuse religious freedom with mere toleration, or shrink it to mean only the freedom to worship. It challenges those who view it simply as “freedom for the religious,” or think that when religion is dismissed, religious freedom can be ignored. As Article 1 of the Global Charter of Conscience declares, religious freedom is “the right to adopt, hold, freely exercise, share, or change one’s beliefs subject solely to the dictates of conscience and independent of all outside, especially governmental control.” Seen this way, freedom of religion and belief (which covers secularist worldviews too) is essential because it involves nothing less that our freedom to be human.
You call “soul freedom” the “golden key” to building a free, just, and equitable public square. How so?
Religious freedom is a foundational human right that should be guaranteed and protected simply for its own sake. But over and above that, numerous studies show that when religious freedom is respected, there are many social and political benefits, such as civility in public life, harmony in society as a whole, and vitality in the entrepreneurial sectors of civil society. Violations of religious freedom, such as the recent health care mandates hitting Catholic hospitals and other religious employers, are therefore not only wrong, but blind. As such requirements spread, they will cramp, if not kill the goose that lays the golden egg. One day our brave new government officials will go out in the morning and find there is no golden egg—and therefore they must spend more, and grow government even larger, to cover the gap created by the diminishing of the faith-based organizations.
