 If any come unto you and bring not this doctrine, receive him not into your house, neither bid him Godspeed. Now, that doesn't mean you can't bring him in your house to witness to him. To receive means to welcome him as a brother in Christ, as it would mean the counterpart to give him Godspeed and say, God bless you. We're all headed to the same place. You don't believe in the full deity of Christ. You don't believe that Jesus Christ is the virgin-born Son of God and God the Son, co-equal and co-eternal with God the Father, but God bless you. Oh, no.
