Lox you quoted the following from JOHN1:
"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ IS COME in the flesh is of God: "
Frankly, I do not believe that to be true. The false prophets are deceivers and have no problem confessing Jesus. To think we can 'try the spirits' is to already be deceived.
My (never humble) opinion
"Error does not become Truth because it is widely accepted; Truth does not become error, even when it stands alone"
