At the symposium on law and religion in 2014, Michelle Mack said: "Despite what appears to be a near-universal expression of commitment to religious human rights, the frequency-and severity-of religious persecution worldwide is staggering. Although it is impossible to determine with certainty the exact numbers of people persecuted for their faith or religious affiliation, it is unquestioned that "violations of freedom of religion and belief, including acts of severe persecution, occur with fearful frequency." She quotes Irwin Colter, human rights advocate and author as saying "reedom of religion remains the most persistently violated human right in the annals of the species."
