The concept of the sanctity of blood is a significant theme throughout the Bible, underscoring the sacredness of life and the divine ordinances regarding blood. From the earliest chapters of Genesis to the New Testament, blood is portrayed as a powerful symbol of life, covenant, and atonement.

Old Testament Foundations

The sanctity of blood is first introduced in Genesis 4:10, where God confronts Cain after the murder of Abel, saying, "What have you done? The voice of your brother’s blood cries out to Me from the ground." This passage highlights the intrinsic value of life and the divine awareness of bloodshed.

In Genesis 9:4, following the flood, God establishes a covenant with Noah, stating, "But you must not eat meat with its lifeblood still in it." This command underscores the sacredness of blood as the essence of life, a principle that is reiterated in the Mosaic Law.

Leviticus 17:10-14 further elaborates on this principle, where God commands the Israelites, "For the life of the flesh is in the blood, and I have given it to you on the altar to make atonement for your souls; for it is the blood that makes atonement by the life." This passage not only emphasizes the prohibition against consuming blood but also introduces the concept of blood as a means of atonement, a central theme in the sacrificial system.

The Role of Blood in Sacrifices

The sacrificial system outlined in Leviticus and other books of the Torah places significant emphasis on the use of blood for atonement. The blood of animals, offered on the altar, served as a temporary covering for sin, pointing to the need for a more perfect sacrifice. The Day of Atonement, described in Leviticus 16, involved the high priest entering the Holy of Holies to sprinkle the blood of a bull and a goat, symbolizing the purification and reconciliation of the people with God.

Blood in Covenantal Contexts

Blood also plays a crucial role in the establishment of covenants. In Exodus 24:8, Moses takes the blood of sacrificed animals and sprinkles it on the people, declaring, "This is the blood of the covenant that the LORD has made with you in accordance with all these words." This act signifies the binding nature of the covenant between God and Israel, sealed with blood.

New Testament Fulfillment

The New Testament presents the ultimate fulfillment of the sanctity of blood through the sacrifice of Jesus Christ. In the Gospels, Jesus refers to His impending death as the establishment of a new covenant. During the Last Supper, He states, "This is My blood of the covenant, which is poured out for many for the forgiveness of sins" (Matthew 26:28). Here, Christ's blood is depicted as the means of eternal atonement, surpassing the temporary sacrifices of the Old Testament.

The Epistle to the Hebrews expounds on this theme, contrasting the repeated sacrifices of the Levitical priesthood with the once-for-all sacrifice of Christ. Hebrews 9:12 declares, "He did not enter by the blood of goats and calves, but He entered the Most Holy Place once for all by His own blood, thus securing eternal redemption."

Prohibitions and Ethical Implications

The sanctity of blood also carries ethical implications for the treatment of life. Acts 15:20 records the Apostolic decree to abstain from blood, among other things, as a guideline for Gentile believers, reflecting the continued recognition of blood's sacredness in the early Church.

Throughout Scripture, the sanctity of blood serves as a profound reminder of the value of life, the seriousness of sin, and the depth of God's provision for redemption through the blood of Christ.
