Notice what 2 John says :
9 Everyone that pushes ahead and does not remain in the teaching of the Christ does not have God. He that does remain in this teaching is the one that has both the Father and the Son. 10 If anyone comes to YOU and does not bring this teaching, never receive him into YOUR homes or say a greeting to him. 11 For he that says a greeting to him is a sharer in his wicked works.
Even if one could accept that this really means what they say it means, it is those who deny the teaching of The Christ.....not the teaching of The Watchtower Society !
