I ran across a very good summary of the holiday from a Jewish perspective (after all, it was/is a Hebrew holiday - Didn't YHWH originally instruct the Israelites to observe it?). The article appeared on the International Business Times website (You can view the entire piece at this address: http://www.ibtimes.com/rosh-hashanah-2016-5-key-facts-about-jewish-new-year-2424752
Jason Le Miere makes the following points about the meaning of the holiday:
1. It is considered to be the anniversary of the creation of Adam and Eve.
2. It is the Jewish New Year.
3. It is a time to reflect on past behavior and think about the year ahead.
4. It marks the beginning of the Days of Awe (related to self-examination, repentance and Yom Kippur or Atonement).
5. It is a time to consume symbolic foods.
6. It is a day for the blowing of the shofar (ram's horn).
7. The Jewish greeting is paraphrased in English as "may you be inscribed and sealed <in the Book of Life> for a good year."
Hmmm, perhaps it would be appropriate/instructive to do a little more research into Jewish attitudes and traditions regarding one of their chief holidays?
