⁹ Anyone who runs ahead and does not continue in the teaching of Christ^(A) does not have God; whoever continues in the teaching has both the Father and the Son.^{(B) 10} If anyone comes to you and does not bring this teaching, do not take them into your house or welcome them.^{(C) 11} Anyone who welcomes them shares^(D) in their wicked work.

¹⁷ I urge you, brothers and sisters, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned.^(A) Keep away from them.^{(B) 18} For such people are not serving our Lord Christ,^(C) but their own appetites.^(D) By smooth talk and flattery they deceive^(E) the minds of naive people.
