Greek · Strong's G987
βλασφημέω
blasphēméō (blas-fay-MEH-oh)
verb
To speak evil of, revile, or rail against God or others, often with the specific sense of impious utterance.
Blasphēmeō carries the core meaning of speaking words that harm or dishonor, whether directed toward God or humanity. Its semantic range includes general slander and abusive speech, but it frequently elevates to the more serious theological offense of blasphemy against God. This impious speech demonstrates a profound disrespect for divine authority and often involves attributing evil or imperfection to the Most High. In its more general usage, the term can describe defaming or speaking injuriously about other people, a practice strongly condemned in biblical ethics. The context usually clarifies whether the target of the evil speech is divine or human. The Old Testament concept of profaning God’s name or despising the sacred provides a backdrop for understanding the gravity of blasphēmeō in the New Testament. The act of blasphemy not only involves words but reflects a rebellious heart that rejects God’s sovereignty and character. In some contexts, it can also refer to verbal abuse or slander directed towards human figures, especially those in authority or those representing God. This broader application highlights that destructive speech, regardless of its target, is contrary to godly living. This word represents a significant ethical and theological concern in the New Testament, encompassing both the vilification of divine truth and the defamation of human dignity.
