You said....God is capable of creating infinite number of manifestations of itself and hence the pantheism.....
My answer----
God is not pantheistic.
You said....The concept of God did not begin with Jesus and won't end with it.
Throughout space and time different people will continue praying to God (the same God) using different names.
My answer Gengis....
..I realize this is what you believe....
..but there is ONLY ONE GOD.... only ONE.
If you read my post once again I said:
"Christians believe in one God, Hindus too believe in one God, but Hindus also believe that God is capable of creating infinite number of manifestations of itself and hence the pantheism."
According to Hinduism there is ONLY ONE GOD. Although it does not mean that just because he is one so he is incapable of creating infinite manifestations of himself. There is God residing inside all of us and inside every living being, it is because HE IS capapble of creating as many different manifestations of himself as he wishes. Afterall He is the almighty.
