Blasphemy– (Black’s Law Dictionary 6th Ed.): Any oral or written reproach maliciously cast upon God, His name, attributes, or religion [Christianity/ doctrines of Jesus Christ]. In general, blasphemy may be described as consisting in speaking evil of the Deity with an impious purpose to derogate (detract; belittle) from the divine majesty, and alienate the minds of others from the love and reverence of God. It is purposely using words concerning God calculated and designed to impair and destroy the reverence, respect, and confidence due Him as the intelligent creator, governor, and judge of the world. It embraces the idea of detraction, when used towards the Supreme Being, as “calumny” (false and malicious statement; slander) usually carries the same idea when applied to an individual. It is A willful and malicious attempt to lesson men’s reverence of God by denying his existence or his attributes as an intelligent creator, governor, and judge of men, and to prevent their having confidence in him as such. …In English Law, blasphemy is the offence of speaking matter relating to God, Jesus Christ, the Bible, or the Common Prayer, intended to wound the feelings of mankind or to excite contempt and hatred against the church by law established, or to promote immorality.
