The issue is not that you disagree with trinitarian theology. The issue is that, in this exchange, you have consistently treated the term Son as inseparable from a creaturely category—even after it has been explained repeatedly that trinitarians explicitly deny that entailment. At that point, continued use of creaturely terms no longer functions as disagreement with the position being argued—the doctrine of the Trinity—but functions as a misstatement of it. You are (a) importing a category that your interlocutors have explicitly rejected and then (b) arguing against the result.
That is why such terms are being disallowed in this context. It is not a blanket prohibition. You can use creaturely categories to describe the Son in a thread that discusses Eusebian subordinationism or your view. But this thread is discussing the doctrine of the Trinity, not your view. The prohibition is a procedural requirement to prevent category-loading that reduces every use of “Son” into a creaturely framework that the position under discussion does not hold.
Ok that makes sense to me now.
That is exactly what they considered objectionable.
They certainly didn’t believe this person from Nazareth was the Messiah—but then they didn’t believe he was the son of David, either, which is a related messianic title. They clung to their messianic expectations even as the Messiah stood right in front of them.
But such was their erroneous reading of the scriptures, which Jesus was exposing here. He was doing a reductio or an internal critique in order to show the inadequacy of their interpretation of specific messianic texts. Yes, the Messiah would be the son of David. “But notice something,” Jesus essentially said. “Under the inspiration of the Spirit, David himself called him Lord. Weird, right? How can David’s son also be his Lord? Think this through. Take your time. I’ll wait.”
There is a reason why “no one was able to answer him a word” (v. 46). They experienced a theological paralysis because the reductio had them boxed in. Every avenue of escape would require them to deny Scripture itself, which they simply could not do. Scripture said the Messiah would be the son of David. But it also said he would be David’s Lord. Both were scriptural statements, so both had to be true. But how? And yet they also couldn’t admit the deficiency of their interpretation; that would require a radical overhauling of their messianic expectations. They were comfortable with the Messiah being merely the son of David, but they were uncomfortable with the implication that he would be something more than that. The contradiction Jesus forced them to reckon with exposed precisely that implication. Jesus is not rejecting the premise that the Messiah is David’s son; he is rejecting the inference that Davidic sonship exhausts the Messiah’s identity.
The riddle works because the Messiah being the son of David is true—and insufficient. It is not Scripture that is under critique, but rather the Pharisees’ construal of it. The tension lies in their inability to integrate lordship with sonship. No one was able to answer him a word because they couldn’t deny either premise without destroying Scripture. They were boxed in.
Jesus placed two scriptural claims side by side: the Messiah is David’s son (grounded in 2 Samuel 7 and the prophetic tradition), and the Messiah is David’s Lord (grounded in Psalm 110). Both are canonical, authoritative, and non-negotiable. To deny either would be to deny Scripture itself. They are silent not because the riddle is clever but because there is no permissible denial.
No one was able to answer him a word because neither premise could be denied without denying Scripture itself—and their theology had no way to hold both together.
Joseph was not his Father, but he certainly was his father—without which Jesus would have no claim to the Davidic throne. In Second Temple Jewish law and custom, (a) legal paternity establishes inheritance and (b) kingship passes by legal descent. It is no accident that Matthew includes Joseph in Jesus’s genealogical record. Through Joseph he is legally heir to the throne. Through Mary he is biologically descended from David. This is precisely how Jesus fulfills the Davidic promise while avoiding the judicial disqualification placed on Jeconiah’s biological line (Jer 22:30; cf. Matt 1:11-12).
