Q: Luke 9:50 vs Luke 11:23 — "not against you is for you" vs "not with me is against me." No contradiction: both affirm there's no middle ground — you're either in the kingdom or out. The first passage shows the kingdom is bigger than your local group; people can serve Jesus without being part of your organization.

Luke 9:50: disciples tried to stop someone casting out demons in Jesus' name because he wasn't in their group. Jesus says don't stop him. Luke 11:23: whoever is not with me is against me. Both say the same thing: there's no neutral third category. The body of Christ is bigger than any one local church.
