Nobody is perfect. Famous people are put under microscopes.
Nobody is asking or expecting him to be perfect. But the Bible does say that our doctrine should be sound and if someone comes to us who does not have sound doctrine, we should not have anything to do with him.
Hinn has been exposed countless times as a heretic and I don't believe we can consider him a brother in Christ, but must consider him a wolf among the sheep.
Anyone who continues to follow or defend him needs to read 2 John.
There are two kinds of heretics described in the Bible: the functional heretic (that is, one who follows heresy out of ignorance) and the formal heretic (that is, one who knows sound doctrine but rejects it).
While I would like to believe that Hinn's followers are in the former camp (I know that's where I was when I was caught in the WoF trap and hung on Hinn's every word), but when we continue to show them what Hinn teaches and compare it with scripture and they continue to follow him, it becomes clear that they simply don't care about sound doctrine or what the Bible says.
Hinn, clearly, is in the latter camp. He's been corrected many, many times and even repented briefly of his "each member of the Trinity is a trinty" teaching, but then went right back to teaching it.
I think you need to decide which camp you're going to be in: do you follow Hinn because you don't know any better? Or do you know what doctrines the Bible requires of us and just don't care?
