Because covenant theology was a community-wide agreement, and not merely individualistic, the Puritans also believed very strongly in both a social and an ecclesiastical statehood. They felt that religion could never be separated from statehood or government since it would ultimately affect the success of the whole community.
Eventually, the strong belief in ‘covenant theology’ was one of the factors that validated the Revolutionary War in the minds of the early American Colonists. The early American’s believed in the idea of a covenant with the monarch. The king was in covenant with the people to seek after their happiness and well-being. They also picked up on John Locke’s idea of the “right to revolt” if the king was not keeping his side of the covenant to look after the best interest of his subjects. So this seems to be one of the justifications for the Revolutionary War and fighting for freedom from England's rule.
