I think I need to say this...I don't understand why people are so obsessed with what another makes....consider this, when we "judge" these in the OP, determining if they live in excess or not, aren't we just showing our own bias, our own fleshly desires? Our own lack of trust that God will provide?
When we proclaim that a pastor should be paid this or that, isn't it our own flesh that we are looking to for the answers, not God?
If God, in His wisdom allows Copeland and Hinn, and others to acquire great wealth, even on the fleecing of the flock, isn't it His responsibility? If God in His wisdom allows a pastor to live in great poverty, isn't He still the one who gives good gifts? When do we stop worrying about what others have or don't have and start exercising faith over what we have, even if what we have is our own pride and opinions?
~just talking in general, not to anyone in particular, me included~
Point is this, when we are above reproach, we have the right to question what God in HIs wisdom has allowed. Until then, there are things still hidden from us, things we ourselves need to understand...about wealth and want, trust and authority...seems to me we should not be asking if it is right for these men to live in wealth or poverty, but rather what can we learn from them about God and our own Godliness....
Hint: when you serve God for poverty wages, you learn a lot about money and trust and authority that you only thought you knew before.
