It all goes back to the meaning of the word "true" and if there are any other world religions that conform to the Noahide Law. That's where I'm at. What you're describing above is the Baha'i definition of a "true" religion. I'm still trying to get clarity on what is considered "false" according to Judaism, and what is the metric for determining that. Chat with you later,That link did not come up but I will look at it later. I have to run to work now, I mean bike, and it is a long way and I cannot afford to be late...
The CONTEXT of Judaism believing they are the only true religion is that they do not accept any of the Messengers of God (Prophets) that came after Moses, namely Jesus, Muhammad, the Bab and Baha'u'llah. If they do not accept those Messengers as being from God, they cannot SAY they accept those religions as true religions.
The Baha'i Faith accepts Moses, Jesus, Muhammad, the Bab and Baha'u'llah and other Messengers as being true Messengers of God so we believe that their religions are true religions from God, all part of the eternal religion of God that unfolds over time.
