A citation of this assertion would be most convincing.
In The New Jerome Biblical Commentary published about 23 years ago, the statement is made that the Church has made very few official pronouncements or interpretations of scripture.
I think the whole question is a bit too overly interpretive. The entire Old Testament is a precursor or preparation for the arrival of Christ. In The Jewish People and their Scriptures in the Christian Bible, Pope Benedict XVI and the Pontifical Biblical Commission who composed that document assert that the New Testament scriptures would be meaningless without the Old Testament.
And, I would embellish that last sentence with something from the liturgy of the Lord’s Baptism which the Church just observed a week or two ago, where I heard it said that the New Testament really begins with the Baptism of Christ.
The Gospels attest to Christ’s fulfillment of the prophecies of the Jewish Scriptures. Jesus is, if you will, the “new Moses.” Moses as a prophet and law-giver is a precursor of Christ. Moses is mentioned 80 times in the New Testament scriptures (according my count, using Strong’s Exhaustive Concordance).
