Without considering both testaments, neither can be fully understood in the manner in which God intends them to be understood.
The Mosaic Law is best understood when it is divided into: (1) the moral law, (2) the civil law, and (3) the ceremonial law.
Here is a site that has pictures of the Jewish practice of Kapparot. "Kapparot, which is from the same Hebrew root as Yom Kippur and literally means "atonements", is a custom which aims to awaken the drive toward repentance while engaging in charity on the eve of Judaism's central day of prayer. The practice of kapparot using live fowl entails the following: A male or female chicken is taken in hand, corresponding to the gender of the taker or family members on whose behalf they are performing the ritual. Psalm 107:17-20 and Job 33:23-24 are recited and the live bird is swung around the person's head three times. While swinging, the person recites the following three times: 'This be my substitute, my vicarious offering, my atonement. This cock (or hen) shall meet death, but I shall find a long and pleasant life of peace.'"
"When burdened with sins from 2006; just burn them up for a real quick fix." Martin Luther dealt with a Roman Catholic agent who sold indulgences with a catchy ditty. Perhaps the preceeding one might work for the new sellers of quick fix forgiveness. Thursday's "Wall Street Journal" revealed a growing trend in churches and the modern spiritual community. More and more congregations are meeting for a service in which they write the sins and failures of the previous year on a piece of paper. Then, in a heart uplifting ceremony, they burn the pieces of paper to symbolize the doing away of these sins and their readiness to face a new year clean and ready to do better. The ceremony is getting rave reviews from many religious groups.
