It is the work of Progressive Christians Uniting which is based in the greater LA area.

It seeks to embody a progressive form of Christianity in statements, conferences and projects to encourage local churches and their members to think and act in more progressive ways and to show the wider community that there is a more authentic form of Christian faith that that projected by the religious right.

The differences between liberal and progressive Christians is well articulated in the introduction and in the articles that follow.  It is an excellent resource for study groups and for praxis.
