Visit the Center for Concern sponsored web site “Education for Justice” for some very practical resources for celebrating Advent in a spirit of Justice.
The site is relatively expensive in that it asks a $48 annual subscription but from what I have seen it is going to be worth it.

If you would like to sample it you may temporarily use the famvin subscription. The user name is famvin and the password is famvin2. I will change the password in a few days so be sure to check it out soon.
