Blasphemy consists “in uttering against God - inwardly or outwardly - words of hatred, reproach, or defiance; in speaking ill of God; in failing in respect toward him in one’s speech; in misusing God’s name”. The prohibition “extends to language against Christ’s Church, the saints, and sacred things”. Making use of God’s name “to cover up criminal practices, to reduce peoples to servitude, to torture persons or put them to death” is blasphemous too. It is “in itself a grave sin”, and one of the acts that are “always gravely illicit by reason of their object”, whatever the intention or the circumstances.
