The Christian Day of Atonement is based on the English translation of the Hebrew term for the Holy day Jews tend to call Yom Kippur. It begins at sunset Tuesday, September 25, 2012 and ends at sunset September 26, 2012.
In an email link that UCG sent me a few hours ago was the following:
If we are reconciled to God through Christ’s sacrifice, why do we need another Holy Day to teach us about reconciliation? If we are already reconciled, why do we need to fast, as commanded on the Day of Atonement? (Leviticus 23:27Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the LORD. Acts 27:9Now when much time was spent, and when sailing was now dangerous, because the fast was now already past, Paul admonished them,Now when much time was spent, and when sailing was now dangerous, because the fast was now already past, Paul admonished them,). What is this day’s specific significance in God’s master plan for the salvation of mankind?
The Day of Atonement and Passover both teach us about the forgiveness of sin and our reconciliation with God through Christ’s sacrifice. However, Passover concerns the redemption of the firstborn and thus applies most directly to Christians whom God has called in this age, while Atonement carries universal implications.
Moreover, the Day of Atonement pictures an essential additional step in God’s salvation plan not found in the symbolism of the Passover. This step must take place before humanity can experience true peace on earth. All people suffer the tragic consequences of sin. But sin doesn’t happen without a cause, and God makes this cause clear in the symbolism associated with the Day of Atonement.
Satan is the author of sin
The Day of Atonement involves not only the forgiveness of sin; it pictures the removal of the primary cause of sin—Satan and his demons. Until God removes the original instigator of sin, mankind will simply continue to fall back into disobedience and suffering. Although our human nature has a part to play in our sins, Satan the devil bears great responsibility for influencing mankind to disobey God.
Even though many people doubt the existence of a devil, the Bible reveals Satan as a powerful, invisible being who can sway all man-kind. Revelation 12:9And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him…
his influence is so great that he “deceives the whole world.”
The devil blinds people to the understanding of God’s truth. The apostle Paul explained this to the Corinthians: “If our gospel is veiled, it is veiled to those who are perishing, whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them” (2 Corinthians 4:3-4  But if our gospel be hid, it is hid to them that are lost:  In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them…
Christians who struggle to resist Satan and stop sinning fight a spiritual battle against the devil and his demons. Paul explains: “For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness” (Ephesians 6:12For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.NASB).
Paul further explains here that Jesus Christ will deliver us from the influence of the devil (verses 13-18). Of course, God is much more powerful than Satan, but we must do our part by actively resisting the devil and the pulls of the flesh (James 4:7Submit yourselves therefore to God. Resist the devil, and he will flee from you.). The Day of Atonement looks forward to the time during which Satan’s deception will be removed and he will no longer be free to influence and deceive mankind (Revelation 20:1-3  And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.  And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,  And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
The Day of Atonement includes picturing the sacrifice of Jesus Christ and reconciliation to God. It is normally observed with fasting.
It was kept by Jesus and His earliest followers. Should it not also be kept by you?
