A basic summary piece on Jonathan Edwards' view of free will, with a comment about Pilgrims and sex, as quoted:
Puritans had a dim view of extramarital relations, but that was because they had a very high view of sexuality in marriage. Love, like the will, needs boundaries and channels; it needs a trusting and trustworthy context. The scholar Edmund Leites has studied hundreds of Puritan sermons about love and sex (there are many), and he has documented how much they preached about the duties to desire and how they saw the marriage bed as the "other altar of love." But they also knew that love, if it is to be sacred, needs a deep set of moral rudders. It needs to be modeled on the way God loves us. For nurturing awareness of the love of God, a vibrant community of faith is needed. For nurturing the love between persons, a faithful marriage is the context.
