actions that will prevent them from having children. Practices Non-use of contraception Also see: Fertility and Infertility, and Protestant views on contraception Quiverfull adherents maintain that God "opens and closes the womb" of a woman on a case-by-case basis, and that any attempts to regulate fertility are usurpation of divine power. Thus, the defining practice of a Quiverfull married couple is not to use any form of birth control and to maintain continual "openness to children," that is to say, engaging in routine sexual intercourse with no attempt to limit the possibility of conception. This practice is irrespective of the time of the month during the menstrual cycle, and is considered by Quiverfull adherents to be the principal—if not the primary—aspect of their Christian calling in submission to the Lordship of Christ. Proponents of the Quiverfull movement also regard contraceptive pills and other similar contraceptives as unacceptable abortifacients. Some Quiverfull adherents advocate for birth spacing through breastfeeding, so that the return of fertility after childbirth could be delayed by lactational amenorrhea. Family organization, homeschooling, homesteading Also see: Dominionism, and Patriarchy Quiverfull authors and adherents advocate for and seek to model a return to biblical patriarchy. Mary Pride has more recently attempted to distance herself from the patriarchy movement and from a focus on the father's role in training daughters. In a column published in her magazine Practical Homeschooling in 2009, as well as in the afterword to the 25th-anniversary edition of The Way Home, Pride clarified her position that it is primarily mothers, not fathers, who should teach girls about women's roles and duties. As Emily McGowin notes in her 2018 book Quivering Families, however, "[Pride] differentiates herself from these approaches without denying the underlying gender hierarchy and pronatalism." Quiverfull authors typically organize family governance to reflect an "umbrella of protection" with the mother as a homemaker under the authority of her husband and the children under the authority of both. Parents seek to largely shelter their children from aspects of culture deemed adversarial to their religious beliefs. Additionally, Quiverfull families strongly incline toward homeschooling and toward homesteading in a rural area. However, exceptions exist in substantial enough proportions that these latter two items are general and are often idealized correlations to Quiverfull practices and not integral parts of them.
