Some are right, it was indeed done at least once in the scriptures. The key to that was that God actually healed people with the cloth.
If there is no healing, it wasn't from God.
If the person providing the cloth stated it is annointed, and it wasn't an annointing from God resulting in the healing, that leaves few remaining choices.
1. That person flat out lied, and there is no annointing.
2. There is a real annointing, but not one from God. Rather a gift from the other team.
Sad thing is, even if there is a healing, it still doesn't prove it's from God. Then you have to judge the message of the person providing the cloth. If they teach the scriptures correctly, good deal, if they do not, and actually lead away from the clear revelation of the gospel, then they are also from the other team.
And if it's not from God, avoid the person who provided it, basically forever.
