The US Conference of Catholic Bishop's (USCCB) has a "Take Action" site sponsored by the USCCB's Department of Justice, Peace and Human Development (formerly Social Development and World Peace). The URL for the Take Action site is:
http://www.usccb.org/sdwp/takeaction.shtml
There you will find a link to sign up to receive email "Action Alerts" notifying you when an important decision is being made at the federal level on issues of domestic and international justice and peace. You’ll find out what the basic issue is, what Catholic social teaching says about the issue, and what you can do.
The next blog post will alert you to an Action Alert on an Anti-Torture bill.
