The blasphemy is an offense to a divinity. It is an insult or irreverence towards a religion or towards what is considered sacred. It is the defamation of the name of a god. The term blasphemy comes from the Greek “blaptein”, which means to insult, and “pheme”, which means reputation. Blasphemy is also an offensive word or act against any respectable person or thing.
In some countries there are laws in the blasphemy code where penalties may vary depending on their severity. Among these countries are: Germany, Austria, Denmark, Spain, Finland, Ireland, the Netherlands, Switzerland and others. Some countries have tried to reform these laws or repeal them.
In Muslim countries, laws against blasphemy are stricter and the penalties are quite severe, with life imprisonment or even the death penalty.
For Judaism, those who blaspheme must be put to death, according to the book of Leviticus (chapter 24), in the Old Testament.
In Christianity, as Jesus said, written in the Gospel of St. Mark (chapter 3), all kinds of blasphemies are forgiven but he who blasphemes against the Holy Spirit will never get forgiveness, will carry his sin forever.
