Puritan attitudes are based on strict moral or religious principles and often involve disapproval of physical pleasures. Based on Biblical portrayals of Adam and Eve, Puritans believed that marriage was rooted in procreation, love, and, most importantly, salvation. Husbands were the spiritual heads of the household, while women were to demonstrate religious piety and obedience under male authority. Furthermore, marriage represented not only the relationship between husband and wife, but also the relationship between spouses and God. Puritan husbands commanded authority through family direction and prayer. The female relationship to her husband and to God was marked by submissiveness and humility.
