re: #10 000G

What else are they going to write in Wikipedia? How many observant Jews are there, and of that group, how many look to—I don’t even know his name—for guidance? Not many. The two largest groups of observant Jews, Chabad and Aish certainly don’t see this guy as their main authority. Yes, he has some legal power. But all countries have groups with legal power, such as the FCC in the US. If you want to start a radio station, then you have to abide by FCC guidelines.

Regarding your link:

The Chief Rabbinate of Israel (הרבנות הראשית לישראל) is recognized by law [1] as the supreme halakhic and spiritual authority for the Jewish people in Israel.

Even though most people disagree with and disregard every ruling he makes.

It has legal and administrative authority to organize religious arrangements for Israel’s Jews.

Really? Like what, planning a Bar Mitzvah party? What exactly does this statement mean?

It also responds to halakhic questions submitted by Jewish public bodies in the Diaspora.

Who freely do what they want despite the ruling.

I could on, but you get the point.
