"Before the Reformation, the value of sexual intercourse was viewed almost exclusively through the lens of procreation. After the Reformation, the lens widened to embrace the unique joys and pleasures of the covenant companionship marriage provides. Thus, sex could be wholeheartedly enjoyed even if performed without the express intention of conceiving children. This view helped paved the way for acceptance of what are now known as “natural” birth control methods. Yet, neither the Catholics nor the Reformers could ever have fathomed the numerous other options that would arise in light of modern medical advances."
