Andry - I see your point regarding televangelists...I don't know how I feel about that. I guess it's not really my place to judge, especially since I don't personally support them financially...
As far as pastors and evangelists go, it is a misconception that they make enough $$ in their ministries to supply their needs. My senior pastor has to choose between a retirement fund or paying for health insurance for his kids. There are a lot more "small church" pastors struggling to make it than there are Benny Hinns, Joyce Meyers, or even mega-church pastors.
In the Christian church, we seem to always equate ministry with poverty. As in, "I'm going into the ministry, so I guess I'll always struggle financially." And if a pastor dares to get ahead just a little bit - if the pastor's wife is blessed financially by someone and decides to buy an expensive coat instead of more Sunday School supplies, people's tongues will wag.
I had a friend in college whose father was a pastor, and the church did not pay them enough $$ to live on, and yet let them know that they as a congregation would be offended if they sought any government assistance (fuel, medical, etc.) because it was a bruise to their ego.
As someone who grew up in a low income family and listened to prosperity preachers talk about how "if you have enough faith, you'll be rich," when my mom, who has more faith than anyone I know, was struggling to make ends meet, I see how people can get incensed by televangelists who drive Porsches and have mansions.
On the other hand, from a pastor's perspective, I also see that people have unrealistic expectations of pastors in regards to how much they think we should or shouldn't have. Another friend (still another PK) and her family were at a church where the people's idea of a parsonage was a trailer with a hole rusted out in the center of the living room while they lived in mansions down the street from the church.
I agree that there needs to be a healthy balance there...what it is, I don't know! Can't we all just get along?
God Bless!
