There is now a review on Review of Biblical Literature on the most recently published book emerging from the Religious Rivalries seminar of the Canadian Society of Biblical Studies:

Vaage, Leif E., ed. Religious Rivalries in the Early Roman Empire and the Rise of Christianity. Studies in Christianity and Judaism/Études sur le christianisme et judaïsm 18 Waterloo, Ont.: Wilfrid Laurier University Press, 2006.

My own chapter in that volume on the civic context is available online here.

The first of the three volumes from the Rivalries seminar was reviewed here:

Donaldson, Terence L., ed. Religious Rivalries and the Struggle for Success in Caesarea Maritima. Studies in Christianity and Judaism/Études sur le christianisme et le judaïsme 8 Waterloo, ON: Wilfrid Laurier University Press, 2000.

For some reason, the second volume, has yet to be reviewed online:

Ascough, Richard, ed. Religious Rivalries and the Struggle for Success in Sardis and Smyrna.  Studies in Christianity and Judaism.  Waterloo: WLU Press, 2005.

I have one of the chapters on rivalries among associations available online here (Doh! That page isn’t transferred to the new format yet.  Excuse all the mess).
