I found this topic of the study to be very interesting. As Adam Hamilton talked about in the video, it is easy to feel comfortable talking about Judaism because we already know so many of the stories and events from The Old Testament. Their origination is our origination. We didn't talk in class about the function of Atonement in the Jewish Faith. This is such an important aspect of the religion, they have a celebration, Yom Kippur (which is outlined in Leviticus 16:29-30). From what I've read, there is a word Teshuvah that directly translated means return. As in return to the path from which you've strayed. The thing I feel we can learn a lot from Judaism is based on this. They don't simply say "I'm sorry I did that", and go on down the road. There is complete process that includes verbalizing your regret to God, and making a plan to avoid that mistake in the future. Their goal, as should be everyone's, is to never repeat the same transgression again.
