Pornography refers to words of images that cause sexual arousal.

The word pornography comes from the Greek word porniea, where we get the English word fornication which often refers to general immorality. It is also conveyed to communicate someone that is a salve to sex. Although it is used sometimes as a synonym  for adultery, the word often means voluntary sexual intercourse by an unmarried person with someone of the opposite sex (premarital) or in today’s culture of the same sex. The word would include what is know as casual sex, including sex with a prostitute. The Encyclopedia of Ethics, defines pornography as "the sexually explicit depiction of persons, in words or images, created with the primary, proximate aim, and reasonable hope, of eliciting significant sexual arousal on the part of the consumer of such materials." Here is a first, simple definition:

Pornography is any material (either pictures or words) that is sexually explicit. 

In every case, fornication is presented as behavior opposed to the plan and will of God.    Pornography is a spiritual problem, which undermines morality and creates a social problem. Pornography encourages lustful behavior, which for several millions people in the Unites States has become an addiction. Thus at the least, pornography erodes a society’s moral   virtue while, at worst threatens peoples marriages and relationships with others.
