@JLeslie – No, I don’t agree with @Ria777. As you said, God is God. Different names can refer to the same entity. Allah, God, Lord etc. But this is my belief. Scientifically speaking we don’t know whether this single deity exists. There are other beliefs. Some of those other beliefs use personalized Gods, like Moses as depicted in the Old Testament. Still other beliefs use several Gods. Before Abraham, some Hebrews already had additional Gods like Baal. Even during the time of Mose or David some people seemed to have worshiped “false” Gods allegedly leading to defeats or disasters (concept of the intervening God using rewards and punishments).
Yes, I totally agree the less separate we are the better, in particular when it comes to finally burying exclusive rights. Interfaith dialog is important finding common values. Equally important a world philosophy dialog finding common values.
Personally I share more common values with most atheists compared to say, the Christian religious right and people who believe in the vengeful God of the Old Testament. I believe in enlightenment, rationalism, humanism, liberalism, and critical thinking. I know many Christians, Muslims, Jews, Bahai, Hindus and so forth who feel the same.
One key issue for the 21st century is whether forward-thinking people should all become agnostics or atheists or whether they remain religious and support the effort to change religions from within.
