American Values, Religious Voices: Letters of Hope from People of Faith contains 100 letters sent by scholars of religions across the country to the President, Vice President, and 117th Congress for the first 100 days of the Biden administration. Each day from January 20 to April 29, 2021, Buddhist, Christian, Hindu, Jewish, Muslim, and Sikh letter writers showed that those who study and teach our diverse religious traditions have something important to say about our shared American values and the pressing issues of our day. Full of insight and inspiration, the letters offer a sense of hope and unity as they call upon our elected officials and each of us to live up to our nation's highest ideals. Like American Values, Religious Voices, Volume 1, which contains the 2017 letters written during the first 100 days of the Trump presidency, Volume 2 supplements the letters with essays that reflect on the significance of this national, nonpartisan campaign and the values highlighted in the letters. "The Letters in Practice" section adds a new component, providing guidance on how to use the letters in a spiritual practice of reading and writing, in an embodied daily practice, in teaching and interfaith work, and in various forms of civic engagement, including political activism and the arts. We hope you will be inspired to find your own ways to bring the letters to life so the enduring wisdom of our different faith traditions and our country's core values can be a force for good in a fractured world.
