What is the Federal Theology, born in the 17th century in New England? The authoress presents the characteristics of the Puritan Federal Theology, emphasising the significance of the concept of Covenant, which binds a man to God and God to man, in the constituting of a community. The covenants entered into by people are acts of mutual debt raising and of undertaking a mutual obligation to discharge it. It is because a covenant ob-liga-tes that it brings forth a league.
