Blasphemy

n. sacrilege, irreverence, impiety

Blasphemy is the defamation of the name of one or more gods. These may include using sacred names as stress expletives without intention to pray or speak of sacred matters. Sometimes blasphemy is used loosely to mean any profane language, for example in "With much hammering and blasphemy, the locomotive's replacement spring was finally fitted."

(n.)
An indignity offered to God in words, writing, or signs; impiously irreverent words or signs addressed to, or used in reference to, God; speaking evil of God; also, the act of claiming the attributes or prerogatives of deity.
  

To attribute to God that which is contrary to his nature and does not belong to him, and to deny what does or is a false reflection uttered with a malicious design of reviling God.

This offence was enlarged in Pennsylvania and perhaps most of the states by statutory provision. In England all blasphemies against God, the Christian religion, the Holy Scriptures, and malicious revilings of the established church are punishable by indictment.

In France, before 1791, it was a blasphemy also to speak against the holy virgin and the saints, to deny one's faith, to speak with impiety of holy things, and to swear by things sacred. The law relating to blasphemy in that country was totally repealed by the code of 25th of September, 1791, and its present penal code, art. 262, enacts that any person who, by words or gestures, shall commit any outrage upon objects of public worship, in the places designed or actually employed for the performance of its rites, or shall assault or insult the ministers of such worship in the exercise of their functions, shall be fined from sixteen to five hundred francs and be imprisoned for a period not less than fifteen days nor more than six months.

The civil law forbad the crime of blasphemy; for example, to swear by the hair or the head of God; and it punished its violation with death. Si enim contra homines factae blasphemiae impunitae non relinquuntur; multo magis qui ipsum Deum Blasphemant, digni sunt supplicia sustinere.

In Spain it is blasphemy not only to speak against God and his government, but to utter injuries against the Virgin Mary and the saints.
