I had heard in lectures that Catholic theology held that the Christ-event added a sensus plenior (fuller sense) to the texts of the Bible (that is to say, the Old Testament) that they did not have before. Now I’ve actually encountered one of the texts that articulates it:
Further, [the resurrected Jesus] manifested the truth not only by visible signs, but also by proofs appealing to the intellect, such as when “He opened their understanding so that they might understand the Scriptures,” [Luke 24:45] and showed that according to the writings of the prophets He was to rise again. (Thomas Aquinas, Compendium of Theology section 238)
I’ve read the Lucan resurrection scene dozens of times, but it never occurred to me that Jesus, among other things, teaches a reading lesson in the wake of His rising. I dig that.
