Never heard that. Nor is it in the Catholic Encyclopedia under the entries for the Ten Commandments, nor for the entry on "Blasphemy". The 2nd Commandment in both places is clearly reserved to God alone.

However, Can. 1369 provides: "A person who in a public show or speech, in published writing, or in other uses of the instruments of social communication utters blasphemy, gravely injures good morals, expresses insults, or excites hatred or contempt against religion or the Church is to be punished with a just penalty." Of course that's only for Catholics, who should know better.

I wholeheartedly agree. However, the CCC teaches otherwise:

2146 The second commandment forbids the abuse of God's name, i.e., every improper use of the names of God, Jesus Christ, but also of the Virgin Mary and all the saints.
