The concept of the altar as a place of sacrifice is deeply rooted in the biblical narrative, serving as a central element in the worship and religious practices of the Israelites. The altar is a sacred structure where offerings and sacrifices are made to God, symbolizing devotion, atonement, and communion with the Divine.

Old Testament Foundations

The first mention of an altar in the Bible is found in Genesis 8:20, where Noah builds an altar to the LORD after the flood: "Then Noah built an altar to the LORD. Taking from every kind of clean animal and clean bird, he offered burnt offerings on the altar." This act of sacrifice signifies gratitude and worship, establishing a pattern for future generations.

In the patriarchal narratives, altars are frequently constructed by figures such as Abraham, Isaac, and Jacob. Abraham, for instance, builds altars at key moments in his journey, as seen in Genesis 12:7-8 and Genesis 13:18, marking places where God appeared to him and reaffirmed His promises. These altars serve as tangible reminders of God's covenant and faithfulness.

The Mosaic Law further institutionalizes the use of altars, particularly with the construction of the Tabernacle. The altar of burnt offering, described in Exodus 27:1-8, is central to the sacrificial system. It is here that the Israelites present their offerings, as commanded in Leviticus 1:3-9: "If his offering is a burnt offering from the herd, he is to offer an unblemished male. He must present it at the entrance to the Tent of Meeting, so that he may be accepted by the LORD."

Types of Sacrifices

The Old Testament outlines various types of sacrifices, each with specific purposes and regulations. These include burnt offerings, grain offerings, peace offerings, sin offerings, and guilt offerings. Each type of sacrifice is performed on the altar, symbolizing different aspects of the relationship between God and His people.

Burnt offerings, for example, represent complete surrender to God, as the entire animal is consumed by fire. Peace offerings, on the other hand, signify fellowship and thanksgiving, with portions shared between the altar, the priests, and the offerer. Sin and guilt offerings focus on atonement and purification, addressing the need for reconciliation with God.

The Altar in the Temple

With the establishment of the Temple in Jerusalem, the altar becomes a permanent fixture in Israel's religious life. Solomon's Temple, as described in 1 Kings 8, includes a grand altar for sacrifices, underscoring its importance in worship. The dedication of the Temple is marked by an immense number of sacrifices, highlighting the altar's role in national and communal expressions of faith.

Prophetic Critique and Promise

The prophets often critique the misuse of altars and sacrifices, emphasizing that God desires obedience and righteousness over ritualistic offerings. In Isaiah 1:11, the LORD declares, "What is your multitude of sacrifices to Me? says the LORD. I am full of burnt offerings of rams and the fat of well-fed cattle; I have no delight in the blood of bulls and lambs and goats." This prophetic voice calls for a sincere heart and genuine repentance, rather than mere external compliance.

Despite these critiques, the prophets also envision a future where true worship is restored. Malachi 1:11 proclaims, "For My name will be great among the nations, from where the sun rises to where it sets. In every place incense and pure offerings will be brought to My name, because My name will be great among the nations, says the LORD Almighty."

New Testament Fulfillment

In the New Testament, the concept of the altar and sacrifice finds its ultimate fulfillment in Jesus Christ. Hebrews 13:10 speaks of a new altar: "We have an altar from which those who serve at the tabernacle have no right to eat." Christ's sacrificial death on the cross is the perfect and final offering, rendering the old system of sacrifices obsolete. As the Lamb of God, Jesus embodies the ultimate sacrifice for sin, reconciling humanity to God.

The altar, therefore, transitions from a physical structure to a spiritual reality, where believers are called to offer themselves as living sacrifices, as stated in Romans 12:1: "Therefore I urge you, brothers, on account of God’s mercy, to offer your bodies as living sacrifices, holy and pleasing to God, which is your spiritual service of worship."

Symbolism and Legacy

The altar as a place of sacrifice remains a powerful symbol of worship, devotion, and the transformative power of God's grace. It serves as a reminder of the cost of sin, the necessity of atonement, and the profound love of God manifested through the ultimate sacrifice of His Son.
