[Polycarp]

The differences between chastity and celibacy are poorly understood by most people. Celibacy is the state of not being married, so a vow of celibacy is a promise not to enter into marriage but instead to consecrate one's life to service (in other words, "married to God"). Chastity, a virtue expected of all Christians, is the state of sexual purity; for a vowed celibate, or for the single person, chastity means the avoidance of sex. For the married person, chastity means the practice of sex only with the spouse.
