It’s frankly difficult to imagine getting too much of the theme of Jesus in the OT, unless one doesn’t like the Bible.
By evoking great heroes of the past like David and Josiah, Matthew points his readers to the ultimate hero to whom all those stories pointed. For Matthew and his circle of Jewish Christians, Jesus was not an afterthought to Judaism, a distinct and unexpected addition to God’s plan in the Old Testament. Jesus was the goal to which Israel’s lovingly remembered history had pointed.’
Craig Keener, Matthew (2nd ed.), 77. I wrote my dissertation on the genealogy in Matthew’s gospel, and some of my points are similar to the one Keener makes here. But that is one quote that in hindsight it would have been nice to include.
Another way to say this is that
“Christianity did not beleive in Judaism, but Judaism in Christianity.” Ignatius of Antioch, Magnesians 10.3.
