Blasphemy, heresy, and apostasy are interesting sins. Many, many people over the centuries have been executed by the Church for these very sins. Jesus the Christ Himself was crucified because the Sanhedrin believed Jesus guilty of these very same sins. Blasphemy is the sin of insulting or showing contempt or a lack of reverence for God. Heresy is the sin of insulting or showing contempt for the Church’s Dogma. Apostasy is the sin of formally rejecting not only your Church’s Dogma but also God Himself. We have always been fascinated with blasphemy, not only as a sin but as an art form. If a Christian’s faith is on such a shaky foundation that our insults rend their faith completely asunder, then it is not a faith worth cherishing. If our blasphemies against God cause you to question your faith in God, whose sin is greater: ours or yours? From a heretics’ point-of-view, blasphemy is the least among all sins. Murder is a ultimate crime against another human being. Suicide is the ultimate crime against oneself. Treason is the ultimate crime against your country. And in the eyes of the Church, blasphemy is the ultimate crime against God Himself. Apparently, because God is an omnipotent, omniscient, and omnipresent deity, the only injuries that can be inflicted on Jesus are words (these strange utterances unique to the human creature). This is evidenced by the Catechism of the Catholic Church:
Blasphemy is directly opposed to the second commandment. It 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. St. James condemns those “who blaspheme that honorable name [of Jesus] by which you are called.” The prohibition of blasphemy extends to language against Christ’s Church, the saints, and sacred things. It is also blasphemous to make use of God’s name to cover up criminal practices, to reduce peoples to servitude, to torture persons or put them to death. The misuse of God’s name to commit a crime can provoke others to repudiate religion. Blasphemy is contrary to the respect due God and his holy name. It is in itself a grave sin. (Catechism 2148)
But Jesus Himself says, Whosoever speaketh a word [of blasphemy] against the Son of man, it shall be forgiven him! (Mt. 12:32) We have already been forgiven by God and His Only Begotten Son because our blasphemy is the forgivable kind. Are we splitting hairs in search of Biblical loopholes? Yes. But if it gets us out of Hell eternal and into Purgatory, we will take whatever we can.
