Regarding the mention of "some of the scribes," it is likely that these individuals were not from the Sadducee sect since their pride would prevent them from openly acknowledging the Lord's wise response. They were probably Pharisees, who, despite having colluded with the Sadducees to test the Lord, found satisfaction in witnessing the embarrassment of their rivals (see Matthew 22:34 ff.). Mark notes that a scribe, who initially posed a question to Jesus, recognized that the Lord had skillfully addressed the Sadducees (Mark 12:23) and later expressed his agreement openly (Mark 12:32). This very scribe, along with like-minded peers, is referenced by Luke, who notes that after Jesus' rebuttal to the Sadducees, they acknowledged, “Master, you have spoken well.” The Lord, through His profound interpretation of Scripture, compellingly demonstrated the truth of the resurrection, earning admiration even from His adversaries (Luke 20:40-44).
As for the Lord's inquiry about the Messiah—concerning the identity of His Son—this is presented in Luke's account similarly to that in Matthew and Mark. Consult Matthew 22:41-46 and Mark 12:35-37. It is noteworthy that, according to both Matthew and Mark, following the Sadducees’ discomfiture, a scribe approached Him regarding the greatest commandment in the law (Matthew 22:35-40, Mark 12:28-34). It is during this exchange that Mark states no one thereafter dared to question Him, a sentiment echoed by Matthew following the Lord's discussion about His lineage. While Luke omits the dialogue concerning the greater commandment, he emphasizes that the Lord’s question regarding the Christ was self-initiated and not prompted by any questions from others, highlighting their reluctance to challenge Him further after His response to the Sadducees. The question, “How then is He His Son?” is raised, and although Luke does not capture the reaction of the listeners at that moment, his account is supplemented by Matthew and Mark; the former notes that no one was able to respond, and the latter states that the crowd listened to Him with great pleasure.
