Regarding the mention of certain scribes, they likely were not from the Sadducee sect, which would have found it difficult to openly commend the Lord for His wise retort. They were probably Pharisees who, despite their earlier attempts to test the Lord alongside the Sadducees, derived satisfaction from seeing their rivals bested. The Gospel of Mark indicates that a scribe who questioned the Lord later acknowledged the excellence of His answer to the Sadducees and vocally expressed his affirmation. It is possible that this scribe, along with others who shared this supportive view, approached the Lord after His response, stating, "Master, you have spoken well." The Lord effectively demonstrated the truth of the resurrection from Scripture in such a manner that even His adversaries honored Him on this occasion.
The Lord's inquiry concerning the Messiah—regarding whose Son He is— is presented in a manner consistent with Matthew and Mark. Refer to Matthew 22:41-46 and Mark 12:35-37. Following the Sadducees' embarrassment, a scribe from among them questioned the Lord about the greatest commandment in the Law (Matthew 22:35-40, Mark 12:28-34), after which nobody dared to question Him again, a point reiterated by both Matthew and Mark. Although Luke does not recount the dialogue with the scribe concerning the greatest commandment, he indicates that the Lord's question regarding the Christ was self-initiated, and thus, after His response to the Sadducees, he notes that no one dared to ask further questions.
Concerning the Sonship of the Messiah, Luke does not elaborate on the effect of the Lord's question on His listeners, but Matthew and Mark supplement this detail: Matthew states that no one could reply, while Mark notes that the crowd was captivated by Him.
