Thematic Bible: Who partakes with evil

Every person who does not continue to follow the teaching of Christ, but goes beyond it, does not have God [in his life]. [But], the person who continues to follow in the teaching [of Christ] has both the Father and the Son [in his life]. If anyone comes to you [i.e., to your meetings] who does not bring this teaching [about Christ], you should not welcome him into your home or give him [any] greetings [i.e., suggesting approval or endorsement]. For the person who greets him [with approval] participates in his evil deeds [i.e., in his false teaching].
