Exactly. Should Paul Crouch even be considered a televangelist? Businessman is a better word to describe him. In that context, I care about him having a big expensive mansion about as much as I care about Bill Gates owning one.
That's why I run Linux. ;-)
From business and freedom-of-religion standpoint, I would agree. If you make the money legally, go for it. If that's how they and their sheeple choose to worship, that's their right in a free country.
However, from a Christian standpoint, I really question the "gospel" the Crouches are spreading. TBN simply isn't concerned with the Gospel of Jesus Christ. TBN and the Crouches are about turning a profit using the Lord's name, often from people who cannot really afford to send them the money, but do anyway.
Would Jesus or any follower of His ask for money from people, and then turn around and blow it on a personal residence rather than the furtherance of the Gospel of Christ? No.
