Mark 9:38

9:38 he was not following us. This phrase does not deny that the man was not a follower of Jesus; he was casting out demons in Jesus’ name. Probably what is meant is that he does not recognize the authority of the Twelve. Without taking away the prerogatives of the Twelve, but sensing their pride and exclusivism (9:35 note; 10:35–45), Jesus refuses to denounce the one they are talking about. Instead He teaches that the support and fellowship of all who support His cause should be gratefully acknowledged.
