ThiChi,
Confirmed with this one. 1Jo 4:1-3 and 2Jo 1:7-11
1Jo 4:1 Dear friends, don't believe everyone who claims to have the Spirit of God. Test them all to find out if they really do come from God. Many false prophets have already gone out into the world,
1Jo 4:2 and you can know which ones come from God. His Spirit says that Jesus Christ had a truly human body.
1Jo 4:3 But when someone doesn't say this about Jesus, you know that person has a spirit that doesn't come from God and is the enemy of Christ. You knew that this enemy was coming into the world and now is already here.
2Jo 1:7 Many liars have gone out into the world. These deceitful liars are saying that Jesus Christ did not have a truly human body. But they are liars and the enemies of Christ.
2Jo 1:8 So be sure not to lose what we have worked for. If you do, you won't be given your full reward.
2Jo 1:9 Don't keep changing what you were taught about Christ, or else God will no longer be with you. But if you hold firmly to what you were taught, both the Father and the Son will be with you.
2Jo 1:10 If people won't agree to this teaching, don't welcome them into your home or even greet them.
2Jo 1:11 Greeting them is the same as taking part in their evil deeds.
