The department of Public Affairs and Religious Liberty (PARL) works to uphold and advance religious freedom, with a focus on conscience liberty in particular. The human right to have or adopt the religion of one's choosing, to change one's religious beliefs in accordance with conscience, and to publicly or privately express one's religion through acts of worship, observance, practice, witnessing, and teaching are all included in the concept of religious liberty, provided that one respects the equally important rights of others.
