John Calvin Commentary Hebrews 9:12

"nor yet through the blood of goats and calves, but through his own blood, entered in once for all into the holy place, having obtained eternal redemption." — Hebrews 9:12 (ASV)

Neither by the blood of goats, etc. All these things tend to show that the things of Christ so far excel the shadows of the Law, that they justly reduce them all to nothing. For what is the value of Christ’s blood, if it is deemed no better than the blood of beasts? What sort of expiation was made by his death, if the purgations according to the Law are still retained? As soon, then, as Christ came forth with the efficacious influence of his death, all the typical observances must necessarily have ceased.
