Yes, there are flakey churches out there, charismatic and main denominational.
But don't go throwing the baby out with the bath water because of it.
Keep the baby, throw away the bath water.
Do you recall the story of the pharos's magicians copying the miracles of Moses?
The occult works, the devil does his best to imitate.
So don't let the devil deceive you into thinking that a gift from God is a fake.
People always try to copy the real, do not think that tongues is all fake.
It is real and it is scriptural. All the gifts are for now, not just the ones you feel comfortable with.
Remember what Jesus said about the religious hypocrites who did not believe his miracles?
He called it the leaven of the pharisees. It was an and is a unforgivable sin to attribute a miracle from the Holy Spirit to Satan.
That is what is happening when some of these ministers attribute all tongues to Satan.
There is the real and there is the fake.
Don't let some one steal your faith just because he seems to be a religious leader.
Tongues is scriptural, and yes there are fake tongues and much fakery in charismatic churches and main denominational churches.
