I have gathered two wonderful anthologies of peace writings. The first is THE POWER OF NONVIOLENCE: Writings by Advocates of Peace. The introduction is by Howard Zinn. It is a very broad collection of great writing. The other book is CHRISTIAN PEACE AND NONVIOLENCE: A Documentary History, edited by Michael G. Long. It is a chronological collection of Christian writings/documents and commentaries on them. Much of the Church has advocated for peace for nearly 2,000 years. Here are the documents. I hope, if you have a chance, you will enjoy them.
In Christ's love,
Fr. Robert Pax
