[Jhn 10:1, 7-8
1 "Most assuredly, I say to you, he who does not enter the sheepfold by the door, but climbs up some other way, the same is a thief and a robber. ...
7 Then Jesus said to them again, "Most assuredly, I say to you, I am the door of the sheep.
8 "All who [ever] came before Me are thieves and robbers, but the sheep did not hear them.
[2Jo 1:8-11
8 Look to yourselves, that we do not lose those things we worked for, but [that] we may receive a full reward.
9 Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son.
10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him;
11 for he who greets him shares in his evil deeds.
