The three religions mentioned are the heavenly religions. They have basically the same idea about Almighty God. According to these religions there is no god or goddess but Only ONE Almighty God Who alone deserves worship. He is the Sole Creator, Sustainer, Provider, and Ruler of the Universe. Except in Christianity, he has No Son, and has no Parents and no Partner or Associate.
There is only One God in Christianity, Judaism and Islam.
The basis of Judaism, Christianity and Islam is the belief in the ONENESS of Almighty God (Allah - in Arabic).
Same God is worshiped in Judaism, Islam, and Christianity. God is called in Islam (in Arabic) Allah. God is written as Allah in the Arabic versions of the Bible.
Christianity: Son of God (Messiah) Islam: Prophet Judaism: False messiah
Christianity, Islam and Judaism are monotheistic religions, meaning they believe in one god.
The connection between Islam, Christianity and Judaism is that the three religions trace their history to the covenant between God and Abraham.
CHRISTIANITY ISLAM JUDAISM
Christianity, Islam, and Judaism are the main ones. Buddhism focuses on Buddha
Muslims are the followers of Islam that is the religion of Allah (or God in English and same God in Christianity and Judaism). Islam is the oldest God religion in the universe. Islam means full submission to God and to His will. Islam per Torah revelation to Moses is called Judaism. Islam per the Bible revelation to Jesus is called Christianity. Islam per Quran revelation to Muhammad is called the same name Islam as it is the last God religion on earth. Accordingly, Muslims (per Quran revelation to prophet Muhammad) didn't get anything from Judaism and or Christianity. The three religions got their teachings, ritual worships, and morals from the same source that is Allah (or God in English and same God in Christianity and Judaism).
Abrahamic religions include Judaism, Christianity, Islam and the Baha'i faith. Christianity recognize Judaism but not Islam. Islam recognizes Judaism, Christianity but not Baha'i faith. And finally Baha'i faith recognizes Judaism, Christianity and Islam all together. And obviously he did not start anything. He simply preached the word of God, i.e. the holy revelations.
The three major monotheistic religions are Judaism, Christianity, and Islam. These religions believe in one God and have sacred texts such as the Torah, the Bible, and the Quran.
They're similar in the fact that they have one god (Allah in Islam, Yahweh in Christianity.)
