Final answer:
Anne Hutchinson's teachings grew controversial in the Massachusetts Bay Colony due to her criticism of religious practices, her belief in direct religious revelation, and her defiance of authority.
Step-by-step explanation:
The teachings of Anne Hutchinson grew controversial within the Massachusetts Bay Colony due to several reasons. Hutchinson criticized the evolving religious practices in the colony and believed that the Puritan ministers taught a shallow version of Protestantism that focused on hierarchy and actions rather than grace. She also claimed to have direct religious revelation, which challenged the authority of the male ministers. These beliefs and defiance of authority led to her being tried, convicted, and eventually excommunicated and banished from the colony.
