Blasphemy

Blasphemy - (Easton's Bible Dictionary)

In the sense of speaking evil of God this word is found in Ps. 74:18; Isa. 52:5; Rom. 2:24; Rev. 13:1, 6; 16:9, 11, 21. It denotes also any kind of calumny, or evil-speaking, or abuse (1 Kings 21:10; Acts 13:45; 18:6, etc.). Our Lord was accused of blasphemy when he claimed to be the Son of God (Matt. 26:65; comp. Matt. 9:3; Mark 2:7). They who deny his Messiahship blaspheme Jesus (Luke 22:65; John 10:36).

Blasphemy against the Holy Ghost (Matt. 12:31, 32; Mark 3:28, 29; Luke 12:10) is regarded by some as a continued and obstinate rejection of the gospel, and hence is an unpardonable sin, simply because as long as a sinner remains in unbelief he voluntarily excludes himself from pardon. Others regard the expression as designating the sin of attributing to the power of Satan those miracles which Christ performed, or generally those works which are the result of the Spirit's agency.

Blasphemy - (Webster's 1828 Dictionary)

BLAS'PHEMY, n. An indignity offered to God by words or writing; reproachful, contemptuous or irreverent words uttered impiously against Jehovah.

Blasphemy is an injury offered to God, by denying that which is due and belonging to him, or attributing to him that which is not agreeable to his nature.

In the middle ages, blasphemy was used to denote simply the blaming or condemning of a person or thing. Among the Greeks, to blaspheme was to use words of ill omen, which they were careful to avoid.

1. That which derogates from the prerogatives of God. Mark 2.
