Could the Abrahamic religions unite?

Religion in its forms differ too much to unite

Not in this lifetime. Maybe in the next.

Could the Abrahamic religions unite?
They could if they wanted to. Do you think they want to?

Wanted to? That means far too much compromise for those religions. There are not only the three basic religions of Judaism, Islam, and Christianity but there are smaller religions such as the Baha'i, Druze, and those from regions of India and East Asia (that identify with the Abrahamic Religion).

Who would meditate all that?

Yes, perhaps in the world after this we will find we all were right in some form and do all live together.

Now there are some areas where the groups do work together, in some neighbor projects, but this is rare and more for civil things.

It does seem impossible,but then I do believe that a time will come when all those who believe in the Almighty will join forces and stand for the truth.

Who would meditate all that?
I figure when the time for harmony is right, Big Daddy God will knock some heads together and administer a few well-placed dope slaps, and everybody will get a lot more agreeable and a lot less self-righteous in a big hurry. Maybe that's what the much ballyhooed awakening of 2012, coinciding with the end of the Mayan calendar is all about. I can hardly wait.

Judaism is what the Islamic and christian religions formed out of, why all the fighting?

I'm not sure if you are familiar with American network TV. ABC began as NBC Blue. These days, can you see ABC and NBC merging? And that's just television over 65 years.

Its been done before!
