American Friends Service Committee
"The American Friends Service Committee (AFSC) is a Quaker organization which includes people of various faiths who are committed to social justice, peace, and humanitarian service. Its work is based on the Quaker belief in the worth of every person, and faith in the power of love to overcome violence and injustice."
As a life-long pacifist I have a natural affinity toward Quakers; my father served with them in a fire camp as a conscientious objector during WW II. Our family has supported the AFSC for many years as one of the most effective organizations of its kind.
