As i said.

Elohim, Yahweh, Jehovah. There is a lot of religions in the Bible coming from it or out of it.

Judaism.
Christianity.
Orthodox Christianity.
Roman Catholic.
Catholicism.
Jehovah Witnesses.

.... I thought there was One God? so there should be only One Religion.

God is mentioned in the Bible can be or is inside of us we are all God's and Goddesses. That is the reason for Judaism and Kabbalah.

Amen comes from Amun Ra, Kabbalah Judaism. Amen locks the Chakras off in the spiritual body.

Our Father Who Art in Heaven is Kabbalah, Judaism. Draws the sexual energy to the loins to the heart.

The Original Aramaic Version of the Lord's prayer is Our Father Who Art Everywhere..

Allah is the God inside of us as well.

Muhammad, Jesus and Zoroaster are as Newport says "conduits" all towards the NON created God.
