Chaste

Chastity is sexual behavior of a man or woman that is acceptable to the moral standards and guidelines of their culture, civilization or religion. The term has become closely associated (and is often used interchangeably) with sexual abstinence, especially before marriage and outside marriage.

The words "chaste" and "chastity" stem from the Latin adjective castus meaning "pure". The words entered the English language around the middle of the 13th century; at that time they meant slightly different things. "Chaste" meant "virtuous or pure from unlawful sexual intercourse" (referring to extramarital sex), while "chastity" meant "virginity". It was not until the late 16th century that the two words came to have the same basic meaning as a related adjective and noun.

For Muslims and many Christians, acts of sexual nature are restricted to marriage. For unmarried persons, chastity is identified with sexual abstinence. Sexual acts outside or apart from marriage, such as adultery, fornication and prostitution, are considered sinful.

In many Christian traditions, chastity is synonymous with sexual purity. Chastity means not having any sexual relations before marriage. It also means fidelity to husband or wife during marriage. In Catholic morality, chastity is placed opposite the deadly sin of lust, and is classified as one of seven virtues. The moderation of sexual desires is required to be virtuous. Reason, will and desire can harmoniously work together to do what is good.

In marriage, the spouses commit to a lifelong relationship which excludes sexual intimacy with other persons. After marriage, a third form of chastity, often called "vidual chastity", is expected of a woman while she is in mourning for her late husband. For example, Anglican Bishop Jeremy Taylor defined 5 rules in Holy Living (1650), including abstaining from marrying "so long as she is with child by her former husband" and "within the year of mourning".
