Sacrilege is the violation or injurious treatment of a sacred object or person. It can come in the form of irreverence to sacred persons, places, and things. When the sacrilegious offence is verbal, it is called blasphemy, and when physical, it is often called desecration. In a less proper sense, any transgression against what is seen as the virtue of religion would be a sacrilege. Is also coming near a sacred place without permission. "Sacrilege" originates from the Latin sacer, sacred, and legere, to steal. In Roman times it referred to the plundering of temples and graves. By the time of Cicero, sacrilege had adopted a more expansive meaning, including verbal offences against religion and undignified treatment of sacred objects.
Most ancient religions have a concept analogous to sacrilege, often considered as a type of taboo. The basic idea is that sacred objects are not to be treated in the same way as other objects.
With the advent of Christianity as the official Roman religion, the Emperor Theodosius criminalised sacrilege in an even more expansive sense, including heresy and schism, and offences against the emperor, including tax evasion.
By the Middle Ages, the concept of sacrilege was again restricted to physical acts against sacred objects, and this forms the basis of all subsequent Catholic teachings on the subject. A major offense was to tamper with a consecrated host, otherwise known as the Body of Christ.
Most modern nations have abandoned laws against sacrilege out of respect for freedom of expression, except in cases where there is an injury to persons or property. In the United States, the U.S. Supreme Court case Burstyn v. Wilson (1952) struck down a statute against sacrilege, ruling that the term could not be narrowly defined in a way that would safeguard against the establishment of one church over another and that such statutes infringed upon the free exercise of religion and freedom of expression.
