D- The Quakers allowed women to become preachers and speak publicly. This was a significant departure from the practices of most other religious groups in America during the 1600s, which typically did not allow women to take on leadership roles or speak in public. The Quakers also rejected the use of formal titles and refused to take oaths, which set them apart from other groups. Additionally, the Quakers believed in the concept of an "inner light," or the idea that every individual had a direct connection to God and did not need intermediaries such as priests or bishops to communicate with Him.
