Religious freedom is a broad term that in the United States is generally used to refer to the rights guaranteed under the Constitution to the free exercise of religion and to the non-establishment of a national church. But the term “religious freedom” has had different meanings throughout history and around the world. It encompasses the rights to believe and to practice a religion, whether according to long-time historical traditions or to newer religious concepts and philosophies. It is a right that is continually on trial across the globe. The struggles for religious freedom and other human rights are indelibly linked, and timeless.
