[1 John 4:1]Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
[1 John 4:2] Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
[1 John 4:3] And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that [spirit] of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
Definition of a Prophet , would be someone that says Prophecy's.
And if it was a Spirit From God then it would Prophecise that Jesus Christ come in the flesh. Mary Propecised those EXACT same words in a number of apparations.
