Beyonce Church in San Francisco.

There is a pastor in San Fran that is using Beyonce music in her church.  She says that Beyonce's songs are like scripture and empower women.  Church attendance in America has decreased by 50% since the 1950's but this church has no problem with attendance in fact it's "sold out".  The Beyonce mass is working.  Beyonce has used religious imagery in her music, videos and live performances so I'm not surprised that someone picked that up and ran with it.  Question is is it legit?  Is this or should this be excepted as an official sermon.  If you watch the video these women say yes.
