Is Elmer Gantry in the house?
No doubt. But not all religious people are pseudo-religious hustlers.
Just like the lastest evolutionary fraud is another example from a long line of evolutionary frauds. But it doesn't mean there aren't some sincere evolutionists that fairly present their observations and conclusions.
That there will be pseudo religious hucksters is acknowedged by scripture.
2 Tim 4 3 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; 4And they shall turn away their ears from the truth, and shall be turned unto fables.
2 Pet 2 1But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction. 2And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of. 3And through covetousness shall they with feigned words make merchandise of you: whose judgment now of a long time lingereth not, and their damnation slumbereth not.
Unfortunately "swift destruction" is not "instantaneous destruction" and these sometime gather a following before self destructing over greedily failing to obey scripture and pay a small permit fee or some other nonsense.
And even a serious preacher is capable of misunderstanding and teaching error.
