Shared ground
Jesus asks the Pharisees to state a basic messianic expectation: the Christ is “David’s son” (a David-linked ruler). They give the standard answer (“Of David”), and Jesus does not directly deny that claim.
Jesus then grounds his counter-question in Scripture by quoting Psalm 110:1. In that psalm, David speaks of someone as “my Lord” (a superior figure) who is invited to sit at God’s right hand and is promised victory over enemies (the “footstool” image). Jesus frames David’s words as spoken “in the Spirit,” emphasizing that David’s wording carries weight.
Where interpretation differs
Who is “my Lord” in Psalm 110 in Jesus’ argument? Many read Jesus as identifying the Christ as more than a merely human descendant—someone greater than David and uniquely exalted at God’s right hand. Others read the point more narrowly: the psalm speaks of a royal figure who outranks David (for example, a future king), and Jesus is exposing that the leaders’ “son of David” category is too small without specifying the full nature of that superior status.
How strong is the title “Lord” here? Some take “Lord” as a clear marker of higher-than-David authority and divine exaltation (especially with “right hand” imagery). Others allow that “lord” can function as an honorific for a human superior; on that reading, the argument still works because an ancestor normally would not call a descendant “my lord.”
Why the disagreement exists
The passage uses a short riddle-like question built on Psalm 110’s wording. It does not spell out every step (for example, exactly how “Lord” should be graded on a scale from polite title to supreme authority). Also, Jesus’ phrase “David in the Spirit” raises questions about whether he is stressing David’s role as an inspired speaker, the psalm’s authority, or both. Those interpretive choices affect how far one thinks Jesus is pushing beyond “David’s son.”
What this passage clearly contributes
Explicitly, the text shows Jesus pressing a tension: the Christ is linked to David (“son”), yet David calls him . That forces an expansion of the expected messiah category. It also portrays Jesus as reading Israel’s Scriptures as pointing to a messiah who is exalted (“sit at my right hand”) and destined to triumph over enemies. Narratively, it closes the public questioning cycle: the leaders cannot answer, and they stop asking him questions (vv. 45–46).
