Final answer:
Anne Hutchinson was banished from the Massachusetts Bay Colony for her controversial religious beliefs and for challenging the authority of Puritan ministers, not because she was thought to be an infidel.
Step-by-step explanation:
Anne Hutchinson left her church, but not because she was considered an infidel. Rather, her departure was due to her controversial beliefs and her challenges to the established religious authority. Hutchinson was critical of Puritan ministers in the Massachusetts Bay Colony, accusing them of preaching a 'covenant of works' instead of a 'covenant of grace.'
Her intellectual pursuits and theological debates, specifically her belief in Antinomianism - the idea that the grace of God once received is not removed by sin - and her claims of direct divine revelation posed a threat to the orthodoxy of Puritan practices. Consequently, Puritan authorities found her guilty of holding false beliefs and banished her from the colony in 1638, which led her to move to Rhode Island and later to New Netherland, where she ultimately met a tragic death.
