What does Hebrews say about the old sacrificial system?

The Epistle to the Hebrews outlines how the Old Testament sacrificial system, involving endless sacrifices by high priests, was but a shadow of the greater reality found in Christ (Hebrews 9:24). Each animal sacrifice served as a temporary measure for sin, while Christ's one-time sacrifice provided true and lasting atonement. With His death, the veil of the temple was torn, signifying that access to the holy presence of God was now available to all believers through Him (Hebrews 10:19-20). Thus, the old system, although significant, was ultimately fulfilled in Christ, making it obsolete.
