The best Jewish definition of ZION I have seen so far.
"Zion is not about Judging other organizations or persons - The Bible was not given to us so we can judge others. It was given as a guide to knowing YHWH, the most High God of your faith. There is only one God however HE is so complex that humans have trouble coming up with descriptions of HIS nature. He is "Eyn Sof" or "unknowable." Whatever your theology or religious point of view, there is ONLY ONE GOD. It is not our place to tell you what is wrong with your religion. We do want to help you know HIM better.
"Zion is not about exclusiveness. - We wish to incorporate the knowledge that YHWH has given us into the knowledge base of your faith regardless the point of view. We do this without criticizing others. By placing truth before a sincere student of the Word of YHWH the student will recognize the truth and the truth will set you free.
"Zion is not ethnically biased. - We pay no attention to ethnicity or cultural heritage. Each ethnic group has its own merit and value. With YHWH there are no illicit people except those, who by their own volition, reject HIM and HIS word. It is not our business to judge this. Our exclusive role is to put the truth out there. We have no other hidden agenda
"Zion is about spreading knowledge of YHWH to all peoples. - There are elements of truth in every religion or it could not stand the test of time. We are not interested in tearing down the truths of your faith. We are however interested in bringing clarity and deeper understanding of the God of your faith and HIS Word.
