Ariz. Const. art. 2, § 12

The liberty of conscience secured by the provisions of this constitution shall not be so construed as to excuse acts of licentiousness, or justify practices inconsistent with the peace and safety of the state. No public money or property shall be appropriated for or applied to any religious worship, exercise, or instruction, or to the support of any religious establishment. No religious qualification shall be required for any public office or employment, nor shall any person be incompetent as a witness or juror in consequence of his opinion on matters of religion, nor be questioned touching his religious belief in any court of justice to affect the weight of his testimony.
