Honorary medium?

Here's an article in the Salt Lake Tribune about Bill Riordan, who describes himself as a Shaolin priest and an honorary minister and medium with the National Spiritualist Association of Churches (NSAC), got fired back in June 2004 from the Salt Lake airport, and is now making a suit indicating that it was due to religious discrimination. What does honorary mean, I wonder...being a medium without an NSAC certification perhaps?  And why wait 3 years to place a lawsuit??
