How does hutchinson’s charge of puritans living by a “covenant of works” support elson’s larger argument regarding puritan law?

(There was a gleam of truth in the charge of Mrs. Hutchinson9 that the Puritans lived under a covenant of works10. This was because they had not yet fully grasped the whole truth of divine revelation. No further proof of the legalistic tendencies of Puritan worship is needed than a glance at their own laws. A man, for example, was fined, imprisoned, or whipped for non-attendance at church services.) this all what I know hopefully will help you
