I just read about this greeting, signed by many religious muslim leaders around the world.

Peace on you all :)  

Defiantly a nice sentiment. It's nice to ease tension with the religions at this time.

Good to do!... Christian church and the Vatican should do the same!...

 I assume you mean Islamic holiday? It would be a bit pointless to do it for Christmas.

The Catholic church has many such documents and letters.

Good going!

 The point is: There should be more dialogue between the Christian- and the Muslimworld.

 It's true. Christians and Muslims (and Jews) are basically cousins when it comes to spirituality and positive dialouge is needed in an increasingly secular, wicked world.

The more secular the better. Religion is absurdity and pretty much is the core of most that has gone wrong in the world these past 200o years.People need to become stronger and stop making up an ultimate guardian so they can make themselves feel as if they have a purpose, identity and a commitment in this world.
