Institutes of the Christian Religion (1559) - John Calvin
Book 2 - God the Redeemer
Chapter 11 - The Difference between the Two Testaments
Sections 4-6 - Truth in the OT conveyed by images & ceremonies, typifying Christ
Section 4 - The meaning of this difference
Christ fulfills the OT ceremonies, as priest in a new order (Heb 7:11; Ps 110:4): eternal (Heb 7:23), established by oath (7:21), changing the covenant (8:6-13). The OT ceremonies were a shadow of the good things to come - Christ (10:1).
The covenant went from old to new when established in Christ's blood:
"This cup is the new covenant in My blood" - Luke 22:20.
Section 5 - Childhood and manhood of the church
The truth was understood unclearly, as a child understands, in the OT
Gal 3:24; 4:1-2.
The Law and Prophets pointed to Christ, the truth, "twinkling afar off."
Lk 16:16; Col 2:3.
Section 6 - Even the great men of faith remained within OT limits
It is still true that few surpass Abraham in faith, but no OT saints discerned the object of faith - Christ - clearly.
Luke 10:24; Matt 13:16; 1 Peter 1:12.
