Doctrine of the False Teachers 2 John 7-9
For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist.
Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward.
Avoid the False Teachers 2 John 10-11
If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him;
for he who greets him shares in his evil deeds.
