2 John 10–11 (ESV) O/H 10 If anyone comes to you and does not bring this teaching, do not receive him into your house or give him any greeting, 11 for whoever greets him takes part in his wicked works. It was an absolute demand that brothers in Christ be supported, fed, and housed by the local congregations they visited. In context of 2John, he is dealing with those proclaiming to be Christians yet are truly deceivers and antichrists. These false prophets, antichrists, and deceivers are not to share in the provision of Christian hospitality. Even the Christian greetings that might be given ever so casually are forbidden in the case of these deceivers. One cannot be a partner of God and a partner of the devil.
