2 John 1:7-11 - Reject Teachers Who Don'T Teach What Christ Taught

⁷ I say this because many impostors have left us to go into the world--men who do not acknowledge Jesus as Christ come in our human nature. It is that which marks a man as an impostor and an anti-Christ. ⁸ Take care that you do not lose the fruit of all our work; rather, reap the benefit of it in full. ⁹ Every one who goes beyond the limits of the Teaching of the Christ has failed to find God; the man who keeps to that Teaching--he has found both the Father and the Son. ¹⁰ If any one comes to you and does not bring this Teaching, do not receive him into your house or welcome him; ¹¹ for the man who welcomes him is sharing with him in his wicked work.
