Prominent Grapevine pastor linked to luxury

He's splashy and hip; his message contemporary and cool. His marketing is  tops in the world of mega-evangelism, making huge waves with his sermon in 2008 titled "Seven Days of Sex."

But in the past few months, it's not theology but physics that may be impacting Young. Namely: What goes up must come down.

One former staff member who says he was close to Young but wishes not to be identified, described it this way: "The lack of accountability. The lavish lifestyle that keeps increasing, while the attendance keeps decreasing."

Over the past few weeks, News 8 has been in contact with a number of individuals who were once close to Young at his massive Fellowship Church in Grapevine, disturbed by his direction and treatment of staff.

Young recently replaced his chief financial officer and replaced him with his personal attorney, business partner and fishing buddy, Dennis Brewer Jr.

With Brewer's help and a complex series of business creations and transactions, Young is now jetting around the country in a French-made Falcon 50 private jet; estimated value, $8.4 million.
