1Jo 4:2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
1Jo 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.
"In the flesh" means entirely within the realm of flesh, not partially, but wholely. Any confession other than Christ being in the flesh is one of anti Christ.
