"What is the Day of Atonement (Yom Kippur)?"

Answer: The Day of Atonement (Leviticus 23:27-28), also known as Yom Kippur, was the most solemn holy day of all the Israelite feasts and festivals, occurring once a year on the tenth day of Tishri, the seventh month of the Hebrew calendar. On that day, the high priest was to perform elaborate rituals to atone for the sins of the people. Described in Leviticus 16:1-34, the atonement ritual began with Aaron, or subsequent high priests of Israel, coming into the holy of holies. The solemnity of the day was underscored by God telling Moses to warn Aaron not to come into the Most Holy Place whenever he felt like it, only on this special day once a year, lest he die (v. 2). This was not a ceremony to be taken lightly, and the people were to understand that atonement for sin was to be done God’s way.

Before entering the tabernacle, Aaron was to bathe and put on special garments (v. 4), then sacrifice a bull for a sin offering for himself and his family (v. 6, 11). The blood of the bull was to be sprinkled on the ark of the covenant. Then Aaron was to bring two goats, one to be sacrificed “because of the uncleanness and rebellion of the Israelites, whatever their sins have been” (v. 16), and its blood was sprinkled on the ark of the covenant. The other goat was used as a scapegoat. Aaron placed his hands on its head, confessed over it the rebellion and wickedness of the Israelites, and sent the goat out with an appointed man who released it into the wilderness (v. 21). The goat carried on itself all the sins of the people, which were forgiven for another year (v. 30).

The symbolic significance of the ritual, particularly to Christians, is seen first in the washing and cleansing of the high priest, the man who released the goat, and the man who took the sacrificed animals outside the camp to burn the carcasses (v. 4, 24, 26, 28). Israelite washing ceremonies were required often throughout the Old Testament and symbolized the need for mankind to be cleansed of sin. But it wasn’t until Jesus came to make the “once for all” sacrifice that the need for cleansing ceremonies ceased (Hebrews 7:27). The blood of bulls and goats could only atone for sins if the ritual was continually done year after year, while Christ’s sacrifice was sufficient for all the sins of all who would ever believe in Him. When His sacrifice was made, He declared, “It is finished” (John 19:30). He then sat down at the right hand of God, and no further sacrifice was ever needed (Hebrews 10:1-12).

The sufficiency and completeness of the sacrifice of Christ is also seen in the two goats. The blood of the first goat was sprinkled on the ark, ritually appeasing the wrath of God for another year. The second goat removed the sins of the people into the wilderness where they were forgotten and no longer clung to the people. Sin is both propitiated and expiated God’s way—only by the sacrifice of Christ on the cross. Propitiation is the act of appeasing the wrath of God, while expiation is the act of atoning for sin and removing it from the sinner. Both together are achieved eternally by Christ. When He sacrificed Himself on the cross, He appeased God’s wrath against sin, taking that wrath upon Himself: “Since we have now been justified by his blood, how much more shall we be saved from God's wrath through him!” (Romans 5:9). The removal of sin by the second goat was a living parable of the promise that God would remove our transgressions from us as far as the east is from the west (Psalm 103:12) and that He would remember them no more (Hebrews 8:12; 10:17). Jews today still celebrate the annual Day of Atonement, which falls on different days each year in September-October, traditionally observing this holy day with a 25-hour period of fasting and intensive prayer, often spending most of the day in synagogue services.

"If Jesus is our atonement, why did He die at Passover instead of the Day of Atonement?"

Answer: Every one of the Old Testament sacrifices typified Christ. The Passover, or paschal, sacrifice was a type of the Lord Jesus Christ as the Lamb of God. The paschal lamb was to be a male, without spot and blemish, and not a bone was to be broken. Jesus fulfilled this picture perfectly. As the Israelites applied the blood of the sacrifice in faith, so we today apply the spotless blood of Christ to the “doorposts” of our hearts. In all these ways, “Christ our Passover has been sacrificed for us” (1 Corinthians 5:7).

An objection sometimes arises that the paschal sacrifice was not considered an atonement; rather, atonement was provided for the Jews via the sacrifices on Yom Kippur (the Day of Atonement). Ergo, Jesus, who was killed at Passover and who is called “our Passover” in the New Testament, could not have been an atonement for sin.

There are two ways to counter this objection. The first is simply to show how Jesus also fulfilled the symbolism of Yom Kippur. Jesus bore our sins in His own body (1 Peter 2:24) and tasted death for every man (Hebrews 2:9). In doing so, He offered a better sacrifice than those of Yom Kippur—better because Christ’s sacrifice was permanent, was voluntary, and did not just cover sin but removed it altogether (Hebrews 9:8-14).

The second counter is to point out that Jewish tradition did indeed view the Passover sacrifice as being expiatory; that is, the lamb removed sin from God’s view. The Passover lamb died under God’s outpoured wrath, thus covering over the sins of the one offering it. Here’s what Rashi, a well-respected medieval Jewish commentator, has to say: “I see the Paschal blood and propitiate you. . . . I mercifully take pity on you by means of the Paschal blood and the blood of circumcision, and I propitiate your souls” (Ex. R. 15, 35b, 35a).

During the tenth and final plague in Egypt, the Passover sacrifice literally saved individuals from death (Exodus 12:23). On the basis of the redemptive offering of the Passover blood, the firstborn lived. Again, Rashi comments: “It is as if a king said to his sons: ‘Know you that I judge persons on capital charges and condemn them. Give me therefore a present, so that in case you are brought before my judgment seat I may set aside the indictments against you.’ So God said to Israel: ‘I am now concerned with death penalties, but I will tell you how I will have pity on you and for the sake of the Passover blood and the circumcision blood I will atone for you’” (Ex. R. 15.12, on Exodus 12.10).

The Passover lambs brought atonement to the believing Jewish households on that signal night of judgment and redemption. Rabbi Abraham ibn Ezra also links the Passover with atonement: “The mark of blood was designed as an atonement for those within the house who partook of the paschal offering, and was also a sign for the destroying angel to pass by the house” (Soncino Chumash, pg. 388).

When John the Baptist saw Christ, he pointed to Him and said, “Look, the Lamb of God, who takes away the sin of the world!” (John 1:29). Jesus is the “Passover lamb” in that He was silent before His accusers (Isaiah 53:7) and in His death bore the wrath of God, preserved the lives of all who trust Him, and gave freedom to the former slaves of sin.
