Mainline Protestantism refers to a group of Christian denominations that emerged from the Protestant Reformation and are characterized by their moderate theological views and commitment to social justice. This tradition includes denominations such as the United Methodist Church, Presbyterian Church (USA), and Episcopal Church. Mainline Protestants often emphasize the importance of reason, tradition, and experience in interpreting the Bible. These churches typically support progressive values, including inclusivity and community service, and they often engage in discussions about contemporary social issues. Mainline Protestantism has played a significant role in American religious life, influencing both faith practices and broader cultural movements throughout history.
