In Rabbis Clorfene and Rogalsky's work "The Path of the Righteous Gentile" they state:<ref>http://moshiach.com/action/morality/blasphemy.php</ref> Blasphemy is the act of cursing the Creator. It is a deed so indescribably heinous that the Talmud, whenever referring to blasphemy, calls it by the euphemistic term "blessing G-d," to avoid directly expressing the idea of cursing G-d, the Father of all.
2. Blasphemy is the only means by which one transgresses the Seven Universal Commandments through the faculty of speech alone.
