For Holy Week we’re having a parade of Catholic sins. Here’s a really, really bad one—in fact, a mortal sin that, if unconfessed, will take you to Hell. It’s blasphemy. The Catholic God is a jealous god—in fact, a horrible megalomaniac—and nothing pisses him off more than slurring his good name. The Catholic Catechism, the official doctrine of the Church, defines blasphemy like this:
2148 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.
2162 The second commandment forbids every improper use of God’s name. Blasphemy is the use of the name of God, of Jesus Christ, of the Virgin Mary, and of the saints in an offensive way.
And here from the Catechism—more official current dogma of the Catholic Church, is what happens if you disrespect God and don’t confess it:
1035 The teaching of the Church affirms the existence of hell and its eternity. Immediately after death the souls of those who die in a state of mortal sin descend into hell, where they suffer the punishments of hell, “eternal fire.” The chief punishment of hell is eternal separation from God, in whom alone man can possess the life and happiness for which he was created and for which he longs.
From Summa Theologica, here’s the sophisticated theologian most loved by accomodationists, Thomas Aquinas, asserting that blasphemy is a sin far greater than murder.
Reply to Objection 1. If we compare murder and blasphemy as regards the objects of those sins, it is clear that blasphemy, which is a sin committed directly against God, is more grave than murder, which is a sin against one’s neighbor. On the other hand, if we compare them in respect of the harm wrought by them, murder is the graver sin, for murder does more harm to one’s neighbor, than blasphemy does to God. Since, however, the gravity of a sin depends on the intention of the evil will, rather than on the effect of the deed, as was shown above (I-II, 73, 8), it follows that, as the blasphemer intends to do harm to God’s honor, absolutely speaking, he sins more grievously that the murderer. Nevertheless murder takes precedence, as to punishment, among sins committed against our neighbor.
It’s beyond belief that Catholics see their god as kind and loving, and yet also see him as someone who, if he’s not given proper respect, will send them down to boil for eternity in molten sulfur. Even the worst boss wouldn’t do that to someone who didn’t show proper deference. The Catholic attitude towards blasphemy is immoral.
