CCPR/C/21/Rev.1/Add.4 page 2 3. Article 18 distinguishes the freedom of thought, conscience, religion or belief from the freedom to manifest religion or belief. It does not permit any limitations whatsoever on the freedom of thought and conscience or on the freedom to have or adopt a religion or belief of one’s choice. These freedoms are protected unconditionally, as is the right of everyone to hold opinions without interference in article 19 (1). In accordance with articles 18 (2) and 17, no one can be compelled to reveal his thoughts or adherence to a religion or belief. 4. The freedom to manifest religion or belief may be exercised "either individually or in community with others and in public or private". The freedom to manifest religion or belief in worship, observance, practice and teaching encompasses a broad range of acts. The concept of worship extends to ritual and ceremonial acts giving direct expression to belief, as well as various practices integral to such acts, including the building of places of worship, the use of ritual formulae and objects, the display of symbols, and the observance of holidays and days of rest. The observance and practice of religion or belief may include not only ceremonial acts but also such customs as the observance of dietary regulations, the wearing of distinctive clothing or headcoverings, participation in rituals associated with certain stages of life, and the use of a particular language customarily spoken by a group. In addition, the practice and teaching of religion or belief includes acts integral to the conduct by religious groups of their basic affairs, such as, inter alia, the freedom to choose their religious leaders, priests and teachers, the freedom to establish seminaries or religious schools and the freedom to prepare and distribute religious texts or publications. 5. The Committee observes that the freedom to "have or to adopt" a religion or belief necessarily entails the freedom to choose a religion or belief, including, inter alia, the right to replace one’s current religion or belief with another or to adopt atheistic views, as well as the right to retain one’s religion or belief. Article 18 (2) bars coercions that would impair the right to have or adopt a religion or belief, including the use of threat of physical force or penal sanctions to compel believers or non-believers to adhere to their religious beliefs and congregations, to recant their religion or belief or to convert. Policies or practices having the same intention or effect, such as for example those restricting access to education, medical care, employment or the rights guaranteed by article 25 and other provisions of the Covenant are similarly inconsistent with article 18 (2). The same protection is enjoyed by holders of all beliefs of a non-religious nature. 6. The Committee is of the view that article 18 (4) permits public school instruction in subjects such as the general history of religions and ethics if it is given in a neutral and objective way. The liberty of parents or legal guardians to ensure that their children receive a religious and moral education in conformity with their own convictions, set forth in article 18 (4), is related to the guarantees of the freedom to teach a religion or belief stated in article 18 (1). The Committee notes that public education that includes instruction in a particular religion or belief is inconsistent with article 18 (4) unless provision is made for non-discriminatory exemptions or alternatives that would accommodate the wishes of parents and guardians.
