Richard Ritenbaugh, examining the Jewish observance of the ten Days of Awe, occurring between Tishri 1 (Rosh Hashana/Day of Trumpets) and Tishri 10, (Yom Kippur/Day of Atonement), points out that, even though there are no biblical instructions to observe the Days of Awe, we may look at their role in considering another view of the Day of Atonement. In the context of Jewish tradition, God allegedly writes three books annually - the Book of Life (in which a rather small number of righteous individual are entered), the Book of Intermediaries (into which most individuals fall), and the Book of Death (for the hopelessly incorrigible). During these ten Days of Awe, if an individual rigidly focuses on his spiritual obligations, repenting of his sins and reconciling with those he has wronged, God will move his name into the Book of Life, allegedly allowing him to return to being a carnal disagreeable person for the rest of the year. Consequently, according to this understanding, ten days of good conduct can wipe out 355 days of bad behavior. As God's called-out ones, we ought to count every day as a day of awe. We also must realize that all sins are sins against God, and that sins against other people do not have less importance.
A recent phenomenon among some Sabbatarians is something called the "Lunar Sabbath," counting the weekly Sabbath from each month's new moon. Charles Whitaker argues that the Lunar Sabbath idea is unbiblical and unworkable, asserting that the traditional weekly Sabbath, observed every seventh day, is correct and in line with God's Word.
In this sermon on the significance of the Day of Atonement, Richard Ritenbaugh teaches that on this day we do no work because most of the work of atonement is done by God Almighty. We fast, afflicting our souls, reminding us how much we depend upon God both physically and spiritually, enabling us to lighten our loads and other people's loads. Fasting puts us in a proper humble and contrite frame of mind, allowing God to respond to us, freeing us from our burdens and guiding us into His Kingdom and His family.
