Jesus is not letting go of his line of reasoning. Reality check: Jesus is the one who inspired Asaph to write this psalm. He knows what he meant when he moved the psalmist to put his thoughts onto the papyrus.
I do not believe God “Elohim” was leading Asaph to write that those who are entrusted with the duty of judging and protecting the people of God, are “Elohim” in the same sense as YHWH himself is, or even “the angel of the Lord.”
But before he wraps this up he is no doubt making his argument iron-clad. At this point his defense is “you can’t overlook or ignore the Scripture. It is from God. That being the case, the psalmist, under the inspiration of God says that God declares “you are gods” to those who occupy a place of importance in the care of his people
Either God calls these people “gods” and by extension potentially all of us, or there is a message that his listeners are missing in their understanding of this passage and of God, for that matter. As those commissioned with the responsibility of protecting the Scriptures, they are now in an uncomfortable position of agreeing with Jesus’ premise and giving credence to his technicality or having to discard with this portion of Scripture. The plot thickens even more.
