In Scripture, blood is the carrier of life itself — "the life of every creature is its blood" (Lev 17:14). This gives blood its profound theological weight: the shedding of blood is the giving of life. The entire sacrificial system of the Old Testament ran on blood — animals slain as substitutes, their blood covering and cleansing sin temporarily, pointing forward to the one perfect sacrifice. The blood of Christ is therefore the climax and fulfillment of all that came before: it is the price of redemption (Eph 1:7), the means of justification (Rom 5:9), the basis of the New Covenant (Matt 26:28), and the ongoing ground of the believer's access to God (Heb 10:19). "Without the shedding of blood there is no forgiveness of sins" (Heb 9:22) — a truth that modern religion finds repugnant but Scripture will not soften.
BLOOD, n. The fluid which circulates through the arteries and veins of animals. In theology, the blood of Christ denotes his death; and the shedding of his blood, his sacrifice for sin. "The blood of Jesus Christ cleanseth us from all sin." 1 John 1:7. Blood is the price of anything — we speak of buying a thing with the blood of Christ, meaning his atoning sacrifice.
Modern liberal theology recoils from the "blood atonement," calling it "cosmic child abuse" or a primitive, violent concept unworthy of a loving God. Hymns about the blood — "There Is a Fountain Filled with Blood," "Nothing but the Blood" — are quietly retired from progressive churches as too graphic or offensive. This theological squeamishness guts the Gospel: remove the blood and you remove the atonement; remove the atonement and you have a Christ who died for nothing but a good example. The offense of the blood is precisely its point — sin is not a trifle to be smoothed over with sentimentality, but a capital crime requiring a substitutionary death.
