I always wonder about rich people who think themselves Christians. Or other Christians who look up to them. Jesus directly states that rich people don't go to heaven when asked.
It is fairly common for preachers to say that money is not the problem -- it's what you do with the money.
I mean you also have mainstream preachers telling you that if your faith is strong enough god will reward you with riches, which has been considered a heresy for at least a thousand years.
So I don't know they should be but preachers may not universally be the experts on this unfortunately.
I have no respect for wealthy christians! At all! Yer boy Jesus was extremely extremely clear about what is expected of you on this front. He was ambiguous and contradictory on some things but not this one.
