Thanks to a commentor for pointing out that the diocese has issued a statement:

A STATEMENT FROM  THE DIOCESE OF PHOENIX

Re: The Praise and Worship Service – Dale Fushek and Mark Dippre
November 27, 2007

On Thanksgiving Day, November 22, 2007, Dale Fushek, a priest of the Diocese of Phoenix on administrative leave, conducted a praise and worship service that was in opposition to directives given to him to cease all public and sacred ministries.  Mark Dippre, a priest who left public priestly ministry to enter into a civil marriage and is not a priest in good standing, also participated in the service. The service was not Catholic nor was it endorsed by the Catholic Church.  We encourage the Catholic faithful to keep the Holy Mass, the ultimate form of praise and worship, as the center of their lives. 

All I can say is that I really, really hope they’re not still paying the guy.
