“He that is not with me is against me. He who doesn’t gather with me scatters.
Matthew 12:30 and Luke 11:23 record Jesus saying, "He that is not with me is against me." Mark 9:40 and Luke 9:50 record Jesus saying the opposite: "he that is not against us is on our part / for us." The two sayings frame neutrality as exclusion in one case and inclusion in the other. Luke records both, so the contradiction is internal to a single gospel.
People have answered this in several ways; GEBible presents them as equal peers.

Examining the tension
What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Usually considered reconciled
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
This is the rare gospel contradiction that the text itself preserves without resolving: Luke includes both sayings, in different contexts, and makes no attempt to reconcile them. The exclusive form — *ho mē ōn met' emou kat' emou estin*, "he who is not with me is against me" (Matt 12:30 // Luke 11:23) — and the inclusive form — *hos gar ouk estin kath' hēmōn hyper hēmōn estin*, "he who is not against us is for us" (Mark 9:40 // Luke 9:50) — are logical converses: one treats neutrality as hostility, the other treats non-hostility as alliance.
The apologetic harmonization (Carson, Blomberg, Bock) is the contextual move, and it is genuinely strong because the two sayings come from distinct source-settings with different referents and audiences. The inclusive saying belongs to the strange-exorcist pericope: the disciples report that they tried to stop a man casting out demons in Jesus' name "because he followeth not us," and Jesus rebukes their sectarianism — an outsider doing the kingdom's work is not to be opposed. The exclusive saying belongs to the Beelzebul controversy, where opponents have just attributed Jesus' exorcisms to Satan; here the point is that when the kingdom is breaking in there is no neutral ground, and those who oppose the work align themselves against it. Critical commentators (Marcus, Fitzmyer, Davies-Allison) readily grant the distinction: the first saying concerns sympathetic outsiders and counsels tolerance; the second concerns active opponents and demands decision. The two are even psychologically coherent as a single stance — generous toward those who aid the cause, uncompromising toward those who attack it.
Where the contradiction reasserts itself is at the level of the proverb. Both sayings have the gnomic, balanced form of free-floating maxims, and that is how they have circulated in Christian rhetoric from antiquity onward — quoted as universal principles about allegiance rather than as situational responses. Read as universal moral axioms abstracted from their narrative settings, they flatly contradict: one cannot consistently hold both that neutrality equals opposition and that non-opposition equals support. Read as context-bound responses to two different situations, they cohere. The text, notably, supplies both readings and does not adjudicate between them.
The most defensible assessment is therefore split by level of analysis. At the historical-Jesus and redactional level — where each saying is read in its own pericope — the harmonization holds and the tension dissolves into a coherent two-sided stance. At the level of the proverbial maxim — which is how most readers and most of the tradition encounter the sayings — the two formulations remain genuine logical opposites. This is a contextual judgment rather than a textual error in either evangelist; the contradiction is a function of decontextualization rather than of the narratives themselves.
Where the critical reading lands: harmonizable in context, contradictory as detached maxims.
