Jews read the Book of Ruth on Shavuot because Ruth’s acceptance of Judaism mirrors the Jewish peoples’ acceptance of the Torah. Ruth chooses the path of Judaism just as the Jews chose to accept the Torah from God. For those of you who don’t read the Torah (or the bible) like me a few months ago, here is the cliff-notes of Ruth’s story . . .
Naomi’s husband dies during a famine, later both of her sons die as well. One daughter-in-law, Orpah, decides to return to her family. Her other daughter-in-law Ruth, chooses instead to stay with Naomi and adopt her faith. Ruth tells Naomi “Wherever you go, I will go…your people shall be my people, and your God my God” (1:16). Eventually, Ruth marries a wealthy landowner and her great-grandson is the famous King David. Ruth is considered the first convert to Judaism. The Book of Ruth teaches love, audacity, and loyalty.
Because of Ruth, on Shavuot Jews also honor Jews by Choice. This is why I believe Shavuot is the perfect day for Jewish NPEs to celebrate their heritage.
