Overview of Bible passages about masturbation:

In the past, Christian leaders have mainly used two Bible passages to condemn masturbation:

Christian groups currently differ in their interpretation of the Greek words "pornea" and "akatharsia," found throughout the Christian Scriptures. These are often translated "fornication" and "uncleanness." Some conservative Christian groups include masturbation as one of many acts that fall within the definitions of fornication and uncleanness. Many liberal Christian churches have a much more restrictive view of the two terms.

A third passage which may deal with masturbation is part of the Mosaic Code, and is contained in Leviticus 15. Verse 16 may be interpreted as referring to masturbation in a matter-of-fact manner. The passage does not condemn the practice. We have only seen one reference to this verse on Christian web sites.

Genesis 38:6-9 -- The sin of Onan:

This passage describes how Tamar's first husband Er was killed by God because he was wicked. Under ancient Jewish tradition, Er's brother Onan was required to marry and engage in sexual intercourse with Tamar. Widows were not asked whether they wanted to remarry. In many cases, the woman would have experienced the sexual activity as a form of rape -- something required by tribal tradition which they had to endure. Similarly, nobody consulted the widow's brother-in-law about his wishes in the matter.

Their first son would be attributed to Er. Because any offspring would not be considered his child, Onan decided to use a common and relatively ineffective contraceptive technique to prevent conception. He employed "coitus interruptus". That is, he disengaged from Tamar just before he ejaculated, and "spilled his semen on the ground." (NIV) God was displeased at this action and killed Onan also -- presumably because he refused to follow Jewish tradition.

This passage was used until recent decades by some Christian groups who maintained that Onan's sin was actually masturbation. The term "Onanism" was coined as a synonym of masturbation. This interpretation is no longer in common use.

I Corinthians 6:9 -- Sins that Paul believes will send you to Hell:

The author, Paul, listed a group of sinful activities. He believed that practicing any one of them would prevent a person from inheriting the Kingdom of God. They would be sent to Hell when they died. This verse has been translated in many ways among the 25 English versions of the Bible that we have analyzed.

One of the condemned behaviors is "malakoi arsenokoitai" in the original Greek. Malakoi means soft. It was translated in both Matthew 11:8 and Luke 7:25 as "soft" (KJV) or as "fine" (NIV) in references to clothing. The actual meaning of arsenokoitai has been lost. Some sources in the early Church interpreted the phrase as referring to people of soft morals; i.e. exhibiting unethical behavior. That may well be the correct meaning, because presumably people from that era would probably have still known the meaning of the word "arsenokoitai." Others in the early Church thought that it meant "temple prostitutes" - people who engaged in ritual sex in Pagan temples. Still others thought that it meant "masturbators." At the time of Martin Luther, the latter meaning was in universal use. But by the 20th century, masturbation had become a more generally accepted behavior, whereas many Christians were concentrating on homosexuality as a despised activity. New Biblical translations abandoned references to masturbators and switched the attack to homosexuals. The last religious writing in English that interpreted 1 Corinthians 6:9 as referring to masturbation is believed to be the [Roman] Catholic Encyclopedia of 1967. ₁

Each Bible translating team seems to take whatever activity that their group particularly disapproves of and inserts it into this verse. To compound their error, they usually do not have the decency to indicate by a footnote that the actual meaning of the word is unknown, and that they are merely guessing its meaning.

Conservative Christians tend to be very concerned about their own salvation and that of their family and friends. It is a pity that one of the behaviors that many Christians feel will cause them to lose their salvation is currently unknown. Many probably fear that they might inadvertently engage in the activity and thus having to spend eternity in Hell.

Leviticus 15:16-18: Go and wash:

Such items as blood, skin blemishes, semen, and menstrual discharge are considered to have negative magical properties by the Hebrew Scriptures (a.k.a. Old Testament). Touching a dead body was also considered to be very polluting. Many injunctions concerning these items were among the 613 commands which comprise the Mosaic Code. A man automatically became ritually unclean any time that he had an ejaculation of semen. Even after washing his body, he and his clothing remained unclean for a period of time. Some acts that caused ritual uncleanliness even required a temple ritual to reverse.

The following three verses are three injunctions from the Mosaic Code. The language of the King James Version sounds rather quaint today, almost four centuries after it was originally translated.

These three injunctions are generally ignored by Christians today.

The meaning of the Greek word "pornea" in the Christian Scriptures (New Testament):

There are 32 verses in the Christian Scriptures that contain the word "pornea" in the original Greek. It is normally translated in the King James Version of the Bible as "fornication." 

The meaning of the Greek words "akatharsia" and "akathartos" in the Christian Scriptures (New Testament):

This word akatharsia, a noun, and akathartos, an adjective, appears in Romans 1:24, 2 Corinthians 12:21, and Galatians 5:19. It is often translated "uncleanness" in some Bible versions.

In the Hebrew Scriptures (Old Testament) a person or a couple might become ritually unclean:
