Matthew 22.34-46 and the Shema

still thinking about the trinity (first talk this Sunday. see previous post for details).

in Deuteronomy 6, we have the Shema: "Hear O Israel, the Lord your God is One." and following that is the command to love your neighbour as yourself.

and then when Jesus in Matthew 22 quotes the command, which sums up all the prophets, it's interesting that he follows it with a question about Psalm 110, one of the most popular texts in the NT for pointing to Jesus' identity as the Christ.

So my question is, is Jesus (or the evangelist) saying something about the Shema, in particular, questioning the identity of Yhwh as a monad, and perhaps making room in the description of Yhwh for the Christ?

or is there not really much of a link between Matt 22.34-40 and Matt 22.41-46? (or is it just a different link?)
