Don't get me wrong. I have nothing against creativity when it comes to cooking, dressing, art, design etc. And I certainly give my very unique opinions when I attend shiurim, Torah or Bible classes. I enjoy hearing the prayers sung to different tunes. But there are some "red lines." I certainly use my own words when thanking G-d in "personal prayer," but I don't make up my own brachot blessings before eating various foods or re-write the Siddur (prayerbook,)Torah or Bible.
Not long ago, because of a cancelled flight, I found myself in the same cab to and from JFK with a young Israeli who is studying in the states. He told me that he's not from a religious family, but he does know basic prayers like Kiddush and the Passover Seder. As an Israeli student on a special scholarship, he can't get back home for Jewish Holidays, so he has tried attending events at the local Hillel. He found them terribly confusing. Kiddish wasn't the Kiddush he knows from home. The Seder wasn't the same Seder, and Prayers were even more confusing.
Reform, Conservative, Reconstructionist and other DIY-Do It Yourself always changing versions of Judaism remove the aspect that kept us one united Jewish People.
Our small neighborhood synagogue here in Shiloh has members from Jewish communities all over the world, the Americas-north and south, France, Majorca, Morocco, Syria, FSU, New Zealand, native Israelis and more. Everyone can take out their old family siddur and use it to pray together, because other than a few minor linguistic differences the prayers, including the order to be said, are the same.
- For thousands of years, Jews all over the world have been praying the same prayers to G-d.
- For thousands of years, Jews all over the world have had the same basic wedding ceremony.
- For thousands of years, Jews all over the world have done the same Brit Milah circumcision on 8* day old baby boys. (*that's when it's medically permitted; sometimes the baby must be circumcised later)
- For thousands of years, Jews all over the world have followed the laws of kashrut, not mixing milk and meat, only eating from certain animals, fish and birds and slaughtering them according to Jewish Law.
Jewish demographics prove that the more Torah observant the family the more Jewish descendants in subsequent generations. It's much harder to perpetuate the family's Judaism when the keeping of Mitzvot, commandments is "optional" or non-standard.
Judaism isn't "broken;" there's no need to "fix it."
